    NEW APPROACH FOR ESTIMATION OF ΔJ AND FOR MEASUREMENT OF CRACK GROWTH AT ELEVATED TEMPERATURE (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Fatigue & fracture of engineering materials & structures 19 (1996), S. 0 
    Details
    ISSN: 1460-2695
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract— The ACPD-method was used to measure crack growth in low cycle fatigue tests at elevated temperature. The material which was investigated at T= 550°C was the ferritic steel 2.25Cr–1Mo. Characteristic values of representative hysteresis loops were determined. The crack growth data were correlated with the effective part of the fracture mechanics parameter ΔJ. A new method for the calculation of ΔJ is proposed.

    Description / Table of Contents: Zusammenfassung Man hat gefunden daß für Armkostahl und für eine Legierung AlCuMgPb, unter Oligozyklischer Müdigkeit, ein Anhalten während einer gewissen Zeit der maximalen Verformung bei jeder Schwingung nicht nur eine Verminderung der Dauerfestigkeit sondern auch eine Vergrößerung der zugehörigen Höchstspannung bewirkt. Eine Gleichung die die Lebensdauer unter dynamischer Belastung in Abhängigkeit von der größten aufgezwungenen Verformung, unter Berücksichtigung der Anhaltungsperioden der Höchstlast, wird vorgeschlagen.
    Notes: Résume On a trouvé que, dans le cas du fer Armco et d'un alliage AlCuMgPb, soumis à des cycles de fatigue oligocyclique, un maintien durant un certain temps de la déformation maximale à chaque cycle entraîne non seulement une diminution de l'endurance mais aussi un relévement de la contrainte maximum correspondante. On propose une relation donnant la vie en fatigue en fonction de la déformation maximale imposée, en tenant compte des périodes de maintien à charge maximale.

    Notes: Abstract Investigations of the discharge for PA-CVD of TiN on steel substrates are carried out using optical emission spectroscopy. A great number of species could be identified in the discharge. The growth rate of dense layers shows a direct dependence on Ti+ intensities. The occurrence of TiN in the discharge leads to f aky, not compact layers, lowering the hardness of the layers.

    Description / Table of Contents: Cyclic Hardening, Yield Surface and Dislocation Arrangement in Low-Cycle FatigueIn Many technical and structural components stress raisers exist which undergo cyclic plastic deformation. Models have been developed to calculate the strain distribution and the resulting life. They are based on the assumptions that Masing-behaviour, isotropic and kinematic hardening are valid with cyclic pasticity. These assumptions have been examined experimentally. An interpretive connection is made between mechanical yield surface and microscopical arrangement of dislocations in the sense of cyclic hardening behaviour.
    Notes: Viele technische Konstruktionen können im Bereich von Spannungskonzentrationen zyklisch plastischen Wechselverformungen unterliegen. Zur Ermittlung der Dehnungsverteilung und der Lebensdauer gibt es Modelle, die auf den Annahmen von Masing-Verhalten, isotroper und kinematischer Verfestigung bei Wechselverformungen aufbauen. Im Rahmen dieser Arbeit werden diese Annahmen experimentell überprüft. Es wird ein Zusammenhang zwischen kontinuumsmechanischer Fließfläche und mikroskopischer Versetzungsstruktur in bezug auf das Verfestigungsverhalten hergestellt.

    Description / Table of Contents: Optimization of the plasma-CVD process for hard coatings by means of optical emission spectroscopyThe deposition of titanium nitride layers by pulsed-DC-PA-CVD was investigated by optical emission spectroscopy. Ti+ and N2+ were controlling factors for layer growth. An occurrence of TiN in the gas phase for higher plasma power deteriorates the layer properties, such as hardness. The analysis of the chemical composition of the layers shows a contrary behaviour of nitrogen and chlorine. The chlorine content affects the hardness of the layers. Chlorine was detected in the discharge in atomic form. No titanium chlorides could be detected. The morphology of the crystal growth is dependent on the deposition parameters.
    Notes: Die Abscheidung von Titannitridschichten mit dem Puls-PA-CVD-Verfahren wurde mit Hilfe der optischen Emissionsspektroskopie untersucht. Ti+ und N2+ wurden als wachstumsbestimmende Spezies ermittelt. Ein Auftreten von TiN in der Gasphase bei höheren Plasmaleistungen verschlechtert die Schichteigenschaften, wie z.B. die Härte. Die Untersuchung der chemischen Zusammensetzung der Schichten zeigt ein gegensätzliches Verhalten von Stickstoff und Chlor. Der Chlorgehalt hat einen starken Einfluß auf die Härte der Schichten. In der Entladung konnte Chlor in atomarer Form nachgewiesen werden. Titanchloride treten nicht auf. Die Behandlungsparameter haben auch einen Einfluß auf die Morphologic des Kristallwachstums.

    Description / Table of Contents: Synthesis of Zr(B,C,N) layers by means of pulsed DC-PACVDIn this study the deposition of Zr(B,C,N) layers by means of low temperature (330°C) pulsed DC plasma assisted CVD process was investigated using a metallo-organic compound as precursor being synthesized in a new way. It is shown that the deposition of Zr(B,C,N) layers is possible with high hardness and adhesion in the investigated parameter window.

Es konnte gezeigt werden, daß die Herstellung von Zr(B,C,N)-Schichten mit guter Härte und Haftfestigkeit im betrachteten Parameterraum möglich ist.
