    Description / Table of Contents: Preparation and Testing of Solid-State Bonded Ceramic-to-Metal-JointsCeramic-to-metal joints were manufactured by solid-state bonding in a R. F.-high-vacuum apparatus. The influence of welding temperature, welding time and welding pressure on the bond strength was investigated for an alumina/niobium-combination consisting of a layered composite ceramic-metal foil-ceramic. As a measure of bond quality the fracture resistance KICV was chosen. KICV date were obtained by the use of 4-point bend tests and tensile tests. For comparison, data are presented concerning the fracture resistance KIC of the bulk alumina and the conventional bond strength of the joints. In addition to the Nb/Al2O3-data, KICV factors are determined for other metal/alumina combinations and for a Zr/Si3N4 joint. The present solid-state bonding apparatus was used for the preparation of the specimens. A device for high-temperature bend testing in a high vacuum was constructed. Some data for the high-temperature bond strength of solid-state bonded joints are given.
    Notes: Keramik-Metall-Verbindungen wurden durch Festkörperschweißen in einer HF-HV-Apparatur hergestellt. Der Einfluß der Herstellungsparameter, Schweißtemperatur, Schweißzeit und Schweißdruck auf die Bindefestigkeit wurde für eine Al2O3/Nb-Materialkombination der Schichtanordnung Keramik-Metallfolie-Keramik untersucht. Als Maß für die Bindequalität wurde der Bruchwiderstand der Verbindung KICV gewählt. KICV wurde im Vierpunkt-Biegeversuch und im Zugversuch ermittelt. Zum Vergleich wurden Bruchwiderstandswerte KIC der Ausgangskeramik und konventionelle Haftfestigkeitskennwerte bestimmt. Außer für Nb/Al2O3-Kombinationen werden für andere, mit der vorhandenen Schweißvorrichtung hergestellten Metall/Al2O3-Kombinationen und für eine Zr/Si3N4-Paarung Bindefestigkeitsdaten angegeben. Eine Vorrichtung zur HV-Hochtemperaturbiegeprüfung wurde gebaut. Einige Daten zur Hochtemperatur-Bindefestigkeit festkörpergeschweißter Verbindungen werden mitgeteilt.

    Description / Table of Contents: Einige metallurgische Beobachtungen zur Herstellung von diffusionsgeschweißten Übergängen zwischen Zircaloy 2 und EdelstahlEs wird ein Verfahren zur Verschweißung von Zircaloy 2 mit Edelstahl durch Ko-Extrusion vorgeschlagen. So hergestellte Schweißverbindungen wurden an der Nahtstelle zwischen Zircaloy 2 und Edelstahl metallographisch und im Rasterelektronenmikroskop untersucht. Außerdem wurden eine chemische Analyse sowie mit der Elektronen-Mikrosonde durchgeführt.Die Ergebnisse dieser Untersuchungen zeigt, daß mit diesem Verfahren eine perfekte Verbindung der beiden Materialien durch mechanische und metallurgische Vorgänge erzielt wird, die besser sein sollte als durch Diffusion bei hohen Temperaturen hergestellte Übergänge.
    Notes: A method of welding stainless steel to Zircaloy 2 by co-extrusion is proposed, and joints of these two metals have been made in this manner. Such a bond was examined at the interface between stainless steel and Zircaloy 2 using metallography, electron microprobe analysis, scanning electron microscopy and chemical analysis. It was found that this method of preparation the joints allow for sound connections characterized by the formation of a type of mechanical and metallurgical bond. These joints could be considered better than those obtained by diffusion at high temperatures.

    Description / Table of Contents: The material selection for tribologically stressed specimen and tools has to be done not only from the view point of economics but also of the consumption of scarce materials and energy.Empirical methods are used for this selection to get a reasonable compromise between surface and bulk functions to satisfy stability and rigidity.By applying system- and stress analysis for the estimation of surface and bulk properties some examples of metallurgical, manufacturing, operational and lubricating aspects to improve the tribological behaviour of components are shown.Using the friction energy for a wear prediction model the calculation of lifetime for dry lubricated roller bearings is possible.
    Notes: Eine funktionsgerechte Werkstoffauswahl für tribologisch beanspruchte Werkzeuge und Bauteile ist nicht nur eine Forderung der Wirtschaftlichkeit, sondern gewinnt auch vor dem Hintergrund der Rohstoff- und Energiesicherung eine zunehmende Bedeutung.Die Werkstoffauswahl tribologisch beanspruchter Werkzeuge und Bauteile wird nach wie vor überwiegend nach empirischen Methoden vorgenommen, wobei häufig Kompromißlösungen zwischen der Oberflächenfunktion und der Grundwerkstoff-Funktion zur Erfüllung der Festigkeits- und Steifigkeitsanforderungen eingegangen werden müssen.Ausgehend von einer methodischen Vorgehensweise einer System-und Beanspruchungsanalyse zur Abschätzung der Oberflächen- und Grundwerkstoffbeanspruchung wurden an verschiedenen Beispielen werkstoffkundliche, fertigungstechnische, konstruktive und schmiertechnische Gesichtspunkte zur Verbesserung des tribologischen Verhaltens von Bauteilpaarungen aufgezeigt.Durch Anwendung eines energetischen Verschleißmodells konnten Berechnungsmöglichkeiten zur Lebensdauerbestimmung feststoffgeschmierter Wälzlager angegeben werden.

    Description / Table of Contents: Results of Creep Tests With Smooth and Notched Specimens of the Steels 20 CrMoV 13 5 and X20 CrMoWV 121Two hydrogen resistant steels, viz. 20 CrMoV 13 5 W.-Nr. 1.7779) and X20 CrMoWV 12 1 (W.-Nr. 1.4935) used for bolts and nuts as well as for pressurized components were tested with respect to their creep resistance. Using smooth and notched specimens creep data for 450°C 500°C and 550°C were established. Steel 20CrMoV 13 5 was investigated in two quenched and tempered states (225…250 HB, 285…310 HB. The tempering treatments of X20 CrMoWV 12 1 (W.-Nr. 1.4935) lead to hardness levels of 215…226 HB resp. 275… 310 HB.Creep tests at 450°C and 500°C resp. at 500°C and 550°C were undertaken with smooth and notched specimens of 20 CrMoV 13 5-resp. X20 CrMoWV 12 1 -steels. At each temperature two resp. three different hardness levels were investigated which were produced by changing the quenching and tempering procedure. The results prove the X20 CrMoWV 12 1-steel to show high ductility in all three Q + T conditions even after long creep tests. This holds true for the 20 CrMoV 13 5-steel in the soft condition and at a test temperature of 450°C only. The creep strength of both steels is about proportional to the ultimate strength of both steels is about proportional to the ultimate strength at room temperature. With regard to the allowable stresses it could be shown that in each case the creep strength for 100.000 hours divided by a safety factor of 1.5 is smaller than the 1% creep limit for the same time.
    Notes: Mit glatten und gekerbten Proben aus den Stählen 20 CrMoV135 und X20 CrMoWV 12 1 wurden Zeitstandversuche bei 450 und 500°C bzw. bei 500 und 550°C durchgeführt Beide Stähle lagen in verschieden harten Ausgangszuständen vor. Die Ergebnisse weisen für den X20 CrMoWV 12 1-Stahl auch nach langen Laufzeiten in allen drei Ausgangszuständen eine hohe Duktilität nach, während dies für den 20 CrMoV 13 5-Stahl nur im weichen Zustand und nur bei 450°C Prüftemperatur gilt. Die Zeitstandfestigkeit ist proportional der Zugfestigkeit des Ausgangszustandes bei Raumtemperatur. In jedem Fall ist der Wert 2/3 der Zeitstandfestigkeit für 100000 h kleiner als der Wert der 1%-Dehngrenze für 100000 h.

    Description / Table of Contents: Model Investigation of the Fibre Reinforcement of Ceramic MaterialsA mechanism for fibre reinforcement of high-modulus brittle materials, in particular ceramics, is investigated both experimentally and theoretically. A simple mathematical formalism representing crack extension in a brittle matrix reinforced by ductile fibres is derived, and characteristic property values, adapted to composite structures, are introduced.Alumina with unidirectional reinforcement by thin 80Ni20Cr wires is used as a model material.The mechanism presented allows to reduce the high sensivity of ceramic materials to cracks. It is necessary for the fibres to bridge matrix cracks under load. For this purpose, the fibres must not be bound too tightly to the matrix, and while a high ductility is certainly of value, it is not a necessity. The efficiency of the mechanism depends on -interface energy and friction at the matrix-fibre interface,-deformation and fracture behavior of the fibre material,-radius of the fibres,-volume fraction of the fibres,-critical stress intensity factor of the matrix,-size of the largest crack.Among these, the fibre radius appears to be the most suitable one for variation with the goal of optimizing material quality.
    Notes: Ein Faserverstärkungsmechanismus für spröde, insbesondere keramische Werkstoffe mit hohem Elastizitätsmodul wird theoretisch und experimentell untersucht.Ein einfache mathematischer Formalismus zur Beschreibung des Rißausbreitungsverhaltens in dementsprechend verstärkten Werkstoffen wird angegeben. Verbundwerkstoffspezifische Kenngrößen werden eingeführt.Als Modellwerkstoff für die experimentellen Untersuchungen dient Aluminiumoxid mit eingelagerten Feindrähten aus 80Ni20Cr.Der beschriebene Mechanismus ermöglicht es, die hohe Rißempfindlichkeit keramischer Werkstoffe herabzusetzen. Die Fasern müssen in der Lage sein, belastete Matrixrisse zu überbrücken. Hierzu dürfen sie nicht zu fest an die Matrix gebunden sein. Duktilität der Fasern ist günstig, aber nicht notwendig. Die Wirksamkeit des Mechanismus hängt ab von -der Grenzflächenergie und -reibung zwischen Fasern und Matrix,-dem Verformungs- und Bruchverhalten der Fasern,-dem Faserradius,-dem Volumenbruchteil der Fasern,-dem kritischen Spannungsintensitätsfaktor der Matrix,-den Abmessungen der größten Risse.Zur Werkstoffoptimierung läßt sich unter diesen Größen am leichtesten der Faseradius variieren.

    Description / Table of Contents: Untersuchung der Spannungsrißkorrosionsanfälligkeit einer Legierung MgAlZn61 in wäßriger Lösung von 3,5% NaCl + 2% K2CrO4 bei Raumtemperatur.
    Notes: Effect of specimen orientation, heat treatment and applied potential on the stress corrosion susceptibility of magnesium AZ61 (Mg-6.3% Al-0.5% Zn-0.20% Mn) alloy in an aqueous 3.5% NaCl + 2% K2CrO4 solution at room temperature was investigated. Stress corrosion times to failure were measured at different values of initial stress intensities using single edge (pre) cracked sheet tensile specimens and a modified tensometer. It was observed that while the specimen orientation has a significant effect on the measured values of stress corrosion threshold stress intensity, KIscc, the effect of varying the quench rate during heat treatment was minimal. Polarization measurements both in stressed and unstressed conditions, failed to reveal any significant effect of the applied stress intensity on the anodic polarization behavior of the alloy. However, measurements made under four different potentiostatic conditions showed a considerable increase in stress corrosion times to failure of the alloy. The results, together with fractographic observations of fractured specimen are discussed in terms of the mechanisms of stress corrosion cracking, in magnesium alloys.

    Description / Table of Contents: Silizium-TechnologieZuerst wird in Kap. 1 eine kurze historische Übersicht gegeben. Im Folgenden wird gezeigt, daß die „Silizium-Technologie“ vom Schwermaschinenbau bis zu mikroskopischen Arbeitsgängen reicht. In Kap. 2…5 wird dies an der Herstellung des Werkstoffs „Silizium“ demonstriert, in Kap. 6 an der Herstellung von diskreten Bauelementen und integrierten Schaltkreisen. In Kap. 7 werden einige Anwendungen in der Leistungs-Elektronik und in der Nachrichten- und Informations-Technik dargestellt. Abschließende Bemerkungen in Kapitel 8 weisen darauf hin, daß trotz aller Wichtigkeit für die Leistungs-Elektronik die wirklich umwälzenden Folgen der Silizium-Technologie auf ihrer Bedeutung für die Computer-Technik beruhen.
    Notes: At first a short historical survey is given in chapter 1. That “silicon technology” comprises a totality reaching from heavy machinery down to microscopic operations, is demonstrated in the chapters 2…5 (production of the material silicon) and 6 (production of devices and integrated circuits). In chapter 7 some applications of these devices in power electronics and in communications- and information-engineering will be described. Finally chapter 8 demonstrates, that in spite of all relevance to power electronics the really very far reaching consequences of silicon technology depend upon its importance to the computer-technics.

    Description / Table of Contents: The Influence of Chemical Composition, Structure, and Mechanical Strain on the Hydrogen Embrittlement of Fine-Grained Low-Alloy SteelsOn specimens from fine-grained low-alloy steels StE 51 and StE 36 strain induced hydrogen embrittlement has been studied under increasing, pulsating, and static load conditions in hydrogen sulphide at various strain rates, gas pressures, gas compositions, and surface qualities. Both steels displayed equal sensitivity compared to mild constructional steels, Hydrogen pick-up occurred only during plastic-deformation of the specimens and led mainly to a decrease of the reduction of area and to the formation of side cracks in the necking zone. This type of embrittlement is important for constructions subjected to pulsating load conditions causing plastic deformation in areas with constructional notches.As part of the research and development project “Corrosion and Corrosion Prevention” this investigation was supported by the Federal Ministry of Research and Technology.
    Notes: An den Feinkornbaustählen StE 51 und StE 36 wurden Versuche zur dehnungsinduzierten Wasserstoffversprödung bei zügiger, bei schwellender und bei ruhender Belastung in Wasserstoff und Schwefelwasserstoff unter Variation der Dehngeschwindigkeit, des Gasüberdruckes, der Gasreinheit und der Oberflächengüte durchgeführt. Beide Stähle verhielten sich nicht grundsätzlich empfindlicher als weichere Baustähle. Eine Wasserstoffaufnahme erfolgte nur im Fließbereich und äußerte sich vornehmlich durch eine Abnahme der Brucheinschnürung oder zumindest durch Nebenrisse im Einschnürbereich. Diese Art der Versprödung kann z.B. für Konstruktionen bedeutsam sein, wenn es unter wechselndem Innendruck an Kerbstellen zu Fließvorgängen kommt.

    Description / Table of Contents: Description of the time dependent stress-strain-behaviour of viscoelastic materials investigated in basic testsAssuming the existence of a mechanical equation of state calculation procedures are investigated in order to formulate the mechanical behaviour of viscoelastic materials in general and independent on the loading form. A case in point would be the derivation of creep behaviour from constant strain rate tensile tests or vice versa. Based on the ordinary log-log-plot for experimental data found in creep tests (constant stress conditions) and/or tensile tests a mechanical equation of state is developed. The results of the application of this equation to describe the mechanical behaviour under constant strain rate, creep and relaxation conditions in basic tests are compared with time-dependent behaviour of polycarbonat.
    Notes: Unter der Voraussetzung der Existenz einer mechanischen Zustandsgleichung werden Rechenverfahren untersucht, mit denen das in Grundversuchen ermittelte mechanische Verhalten viskoelastischer Werkstoffe unabhängig von der Beanspruchungsart beschrieben werden kann. Als Beispiel kann die Bestimmung des Kriechverhaltens aus Zugversuchen mit konstanter Dehngeschwindigkeit genommen werden. Ausgehend von der üblichen doppellogarithmischen Darstellung der Ergebnisse aus Kriechversuchen mit jeweils konstanter Spannung und/oder Zugversuchen wird eine mechanische Zustandsgleichung aufgestellt. Die Ergebnisse der Anwendung dieser Gleichung zur Beschreibung des Werkstoffverhaltens unter konstanter Dehngeschwindigkeit, Kriech- und Relaxationsbedingungen in Grundversuchen sind mit dem zeitabhängigen Verhalten von Polycarbonat verglichen.

    Description / Table of Contents: Dimensioning of Complicated Steel Machine Parts in the Whole Range of Load Cycle and EnduranceThere is given a concept for the early state of dimensioning machine parts, developed by multiple regression from an extensive collection of data. Starting with static strength, it is possible to evaluate fatigue strength of specimens, also notched or of real machine parts under each kind of stresses including preloads and  -  in a first rough approximation  -  also for mechanical- or heat-treated steel parts in the whole range of load cycle and endurance.
    Notes: Es wird ein Dimensionierungskonzept für die frühe Entwicklungsphase vorgestellt, das über multiple Regression aus einer umfangreichen Datensammlung entwickelt wurde. Ausgehend von statischen Festigkeitswerten erlaubt es die Ermittlung der Zug-Druck-Wechselfestigkeit glatter Proben, der Wechselfestigkeit gekerbter Proben und Bauteile unter allgemeinen Beanspruchungszuständen einschließlich Mittelspannungen sowie in einer ersten Näherung auch des Einflusses der Randschicht-Verfestigung im Bereich der Zeit- und Dauerfestigkeit.

    Description / Table of Contents: Cyclic Work Hardening Behavior of the α-copper tin alloy CuSn6.Polycrystalline specimens of the copper-tin alloy CuSn6 have been subjected to strain-controlled single step and two step fatigue tests. In a single step test the cyclic deformation curve at the beginning reveals strong work-hardening which is decreasing in the course of the test. A saturation of the stress amplitude is not observed. In two step tests, the material shows strong cyclic work hardening immediately after the change from low to high amplitudes, After the high amplitude is being changed into a low one, pronounced softening occurs. After changes of the strain amplitudes both these typical reactions of the material are observed up to fatigue crack initiation.
    Notes: An Proben aus der α-Kupfer-Zinnlegierung CuSn6 wurden gesamtdehnungsgesteuerte Ein- und Zweistufenversuche durchgeführt. Zu Beginn der Beanspruchung weisen die Wechselverformungskurven bei Einstufenbelastung einen starken Verfestigungsanstieg auf, der mit wachsender Versuchsdauer kleiner wird. Eine Sättigung der Spannungsamplitude tritt dagegen nicht auf. Bei Zweistufenversuchen wird im Anschluß an einen Wechsel von kleiner zu großer Amplitude eine ausgeprägte Wechselverfestigung beobachtet. Nach einem Wechsel von großer zu kleiner Amplitude wird dagegen eine starke Wechselentfestigung gemessen. Bei wiederholten Amplitudenwechseln charakterisieren diese Ver- und Entfestigungsvorgänge das Werkstoffverhalten bis zum Probenanriß.

    Description / Table of Contents: Fracture Mechanical Considerations on the Effect of Hot Cracks.There exists a lot of literature (1, 2) concerning the mechanisms of the origin of hot cracks. Something essential about the effects of hot cracks on the mechanical behaviour of components hardly can be found. These hot cracks can be valuated only by a quantification of the cracks and by an estimation of their behaviour under operational loadings.It is shown how by means of fracture mechanic material laws and calculation methods the growth of hot cracks under operational conditions can be evaluated. By a simple example of a fatigued vessel the systematic procedure is demonstrated and the results of calculation are explained. This procedure can be applied on the most technical problems as the operational stresses generally are below the yield point. For the region of the yield point and above it neither experimental nor theoretical results are available at the moment.The possibility of simplified calculations of burst stress of vessels is mentioned, which is derived from experiments. Experimental data (11) confirm the chosen hypothesis in so far as the burst stress can be realistically or rather conservatively evaluated by this method.It is concluded: With regard to the fact of unavoidable hot cracks for some certain austenitic steels the authors are convinced that basing on the examples and using the well known data of an austenitic steel as well as modified fracture mechanical rules the up to now empirically assumed stability of hot cracks is practically existent against intolerable crack growth. The given examples make it quite significant that the tolerable defect can be rather big without any critical consequences.If the operational conditions are at or above the level of the tolerable stresses, then safety precautions exist in so far as by means of non destructive - for instance during inservice inspections - volumetric examinations can be carried out. This will enable the detection of a critical defect or of one which becomes critical. Whilst the classic hot crack ranges in a micro dimension and therefore remains undetectable for the non destructive testing methods available at present the increased defect is detectable. Furtheron it should be pointed out that this detectable defect will surely be below the critical size and therefore will not be dangerous.
    Notes: Es wird gezeigt, wie mit Hilfe bruchmechanischer Werkstoffgesetze und Berechnungsmethoden das Wachstum von Heißrissen unter betrieblichen Beanspruchungen berechnet werden kann. Anhand eines einfachen Beispiels wechselbelasteter Behälter, die mit konstanter Amplitude be- und entlastet werden, wird das systematische Vorgehen demonstriert und das Resultat der Berechnung erläutert.Unter Berücksichtigung der Tatsache unvermeidbarer Heißrisse bei bestimmten austenitischen Werkstoffen wird auf Grund der gewählten Beispiele, d. h. bezogen auf einen benannten Werkstoff und modifizierten bruchmechanischen Betrachtungen, dargelegt, daß die bislang mehr oder weniger empirisch angenommene Beständigkeit gegen unzulässiges Rißwachstum tatsächlich weitgehend gegeben ist. Die hier aufgezeigten Beispiele lassen deutlich erkennen, daß der zulässige Fehler ziemlich groß sein kann, ohne kritische Folgen zu bewirken.

    Description / Table of Contents: Study on the Application of the Fracture Mechanics Concept to Ductile Materials-Fracture Behavior of Rigid PVCThe fracture behavior of ductile materials cannot be treated by the methods of linear elastic fracture mechanics concept. For these materials the application of extended theories, which consider the non-linear stress-strain-relationship, is necessary.The test results being reported here have been obtained from rigid blue colored PVC. CT-specimens of different sizes were tested in tension at different loading rates. Above a certain strain level, the material shows crazing. This makes it possible to determine the plastic zone size. The relatively low Young's modulus originates in great deformations of the specimen. The deformation can therefore be measured with great accuracy.During the tests, a great number of quantities were registered. From these quantities the stress intensity factor, crack opening displacement, I-Integral and so on were calculated. The applicability of the results, in order to describe the fracture behavior of ductile materials, is being discussed.
    Notes: Das Bruchverhalten von duktil brechenden Materialien läßt sich nicht mit den Methoden der linear-elastischen Bruchmechanik (LEBM) beschreiben. Für derartige Materialien sind Theorien der erweiterten LEBM und der Fließbruchmechanik (FBM) anzuwenden, die sich zum Teil auf geometrische Größen stützen, deren experimentelle Bestimmung im allgemeinen mit Problemen verbunden ist.Im Rahmen dieser Arbeit erfolgt eine Überprüfung der BM-Theorien im Hinblick auf ihre Verwendbarkeit auf duktile Werkstoffe, wobei sich die Phänomenologie des Versuchswerkstoffes als hilfreich erweist. Das hier verwendete, eingefärbte PVC-hart besitzt die Eigenschaft, auf örtliches Überschreiten eines Beanspruchungsniveaus infolge crazing mit Farbveränderungen in plastischen Bereichen zu reagieren. Ferner nehmen die geometrischen Größen der unterschiedlichen BM-Theorien unter äußerer Beanspruchung durch den gegenüber metallischen Werkstoffen niederen E-Modul relativ große Werte an. Diese geometrischen Größen (Rißöffnung, Form und Ausdehnung der plastischen Zone) wurden auf optischem Wege registriert und nach einer Auswertung zusammen mit weiteren Meßgrößen den verschiedenen bruchmechanischen Theorien zugrunde gelegt.Die aus diesen Theorien gewonnenen Kennwerte werden verglichen und in eine Abschätzung über ihre Verwendbarkeit einbezogen.

    Description / Table of Contents: Pilot Tests with a Directionally Solidified Eutectic SuperalloySeveral vanes of a directionally solidified eutectic superalloy Co—Cr7C3 (40.7 mass% Cr, 2.4% C, rest Co) have been tested for 18 000 hrs in a stationary gas turbine plant. The average material temperature was 700 °C with maximal values at 780 °C. The vanes were demounted after 900 operation cycles and were given a thorough metallographic investigation. Due to non-constant eutecticity over the length of the blade the following effect was observed: The purely eutectic microstructure stably survived the 18 000 hrs test (lower part of the blade). That part of the blade exhibiting off-eutectic (matrix-rich) micro-structure showed carbide transitions (Cr7C3 → Cr23C6) which, in turn, induced coagulation of the carbide fibers. It is concluded that microstructural stability in Co—Cr7C3 alloys is being favored by homogeneous eutectic compositions deviating from the pseudoeutectic point towards the direction of C-rich alloys only on the eutectic trough.
    Notes: Mehrere Leitschaufeln einer gerichtet erstarrten eutektischen Superlegierung (Co-Cr7C3 mit 40,7 Masse% Cr, 2,4% C und Rest Co) wurden über eine Dauer von 18 000 h im Betriebsversuch (stationäre Gasturbine) getestet. Die durchschnittliche Materialtemperatur betrug 700 °C mit maximalen Werten um 780 °C. Nach 900 Betriebszyklen wurden die Schaufeln ausgebaut und einer gründlichen metallografischen Prüfung unterzogen. Aufgrund einer zum oberen Schaufelende hin abnehmenden Eutektizität des Gefüges (zunehmende Menge an γ-Primärdendriten) wurde folgender Effekt beobachtet: Die reineutektischen Bereiche überdauerten den Langzeittest unbeschadet; die untereutektischen Bereiche zeigten Karbid-Umwandlungsreaktionen (Cr7C3 → Cr23C6), welche wiederum Reifungsphänomene der Fasern induzierten. Es wird gefolgert, daß Stabilität dann zu erwarten ist, wenn homogen eutektische Gefüge vorliegen. Abweichungen vom quasi-eutektischen Punkt sind nur in Richtung C-reicher Zusammensetzungen auf der eutektischen Rinne gestattet.

    Notes: Multilevel rotating-bending block tests were performed and the effect of stress peaks on the damage sum of notched aircraft material specimens was investigated. Test results were compared from the viewpoints of the residual stress concept and of the non-linear, stress-dependent damage-cumulation approach.The residual stress concept seems to be valid not only for nonsymmetrical axial loading but also for some rotating-bending loading sequences, when stress peaks are acting. The non-linear stress-dependent damagecumulation approach is in good qualitative agreement with rotatingbending test results, in the case where the role of residual stresses is negligible.
