    Fatigue behaviour of metallic fibre-reinforced materials: a study of steel fibre-reinforced silver (1982)

    Notes: Abstract Low-cycle fatigue tests were performed on silver matrix-steel-fibre-reinforced composites (FRC) with unidirectionally aligned fibres of constant volume-fraction,V f=0.35. The influence of various material parameters, namely the fibre and matrix strengths, the interfacial bond strength and the mean fibre diameter, was examined. Low-cycle fatigue hardening and softening of FRCs deviate from the behaviour expected from the properties of the components. The differences are mainly based on a specific deformation or recrystallization structure of the composite matrix. The shapes of the stress—strain hysteresis loops are discussed qualitatively and compared to the experimental results. The comparison of fatigue life for different material conditions shows that the design of low-cycle fatigue-resistant metallic-fibre composites requires material criteria similar to those known to be responsible for high ultimate tensile strengths. The criteria may be varied if the composites are subjected to high-cycle fatigue loading.

    Notes: Abstract Fatigue damage and crack propagation modes in composites with unidirectionally aligned fibres may be affected by several variables such as fibre and matrix strength, fibre—matrix interfacial bonding and possible fluctuations in the strength of the reinforcing fibres. The influence of the different parameters on the behaviour of metallic fibre-reinforced materials was investigated up to 108 cycles in a model compound of steel-fibre-reinforced silver. The fatigue tests were carried out at a frequency of 20 kHz using an ultrasonic equipment. Two fundamentally different failure mechanisms and several transitional modes have been observed: (a) failure by nucleation and propagation, usually of one matrix fatigue crack, with simultaneous failure of the reinforcing fibres, (b) failure by gradual accumulation of matrix and interface fatigue damage and fibre-inhibited propagation of the final fatigue crack. The occurrence of both mechanisms depends mainly on the development of the local stress conditions when a matrix fatigue crack is approaching a fibre. This is discussed in terms of a simple model. Additionally, the effect of the failure mechanism on fatigue life and on the design of an appropriate failure criterion is considered.

    Description / Table of Contents: Clad Metals for Electrical Engineering. Materials with optimum properties for conducting springs can be produced by cladding a metallic sheat of high electrical conductivity between two sheats of a metal with high stiffness.Using suitable cladding components, thermo bi metals with different electrical resistance can be produced without essential variation of deflection and force. With this it is possible, to use groups of devices with uniform mechanical construction for different currents, which means a good technical as well as economic solution.High prices of noble metal based contact materials have led to the production of contact bimetals some years ago. Inspite of higher production costs these materials can be used very economically.
    Notes: Durch geeignete Anordnung hochfester und hochleitfähiger Komponenten in einem Schichtverbundwerkstoff lassen sich Werkstoffe mit optimalen Eigenschaften für stromführende Federn herstellen. Durch Verwendung geeigneter Plattierungskomponenten können Thermobimetalle mit unterschiedlichem elektrischen Widerstand ohne wesentliche Veränderung der Ausbiegung und der Kraftwirkung hergestellt werden. Somit ist es möglich, Gerätegruppen mit gleichem mechanischen Grundaufbau für verschiedene Stromstärken zu verwenden und damit technisch und wirtschaftlich günstige Problemlösungen zu erzielen.Der hohe Preis der Kontaktwerkstoffe auf Edelmetallbasis führte schon vor vielen Jahren zur Herstellung von Kontaktbimetallen. Trotz höherer Formkosten sind diese Werkstoffe in den meisten Fällen besonders wirtschaftlich einsetzbar.

    Description / Table of Contents: Explosive Welding as a Technique for Cladding of Precious MetalsThe method of explosive welding and the importance of the cladding parameters are described. The “Explosive Weldability Window” is experimentally determined for the material combination AgCu 10/Fe. The behaviour of explosive claddings produced under different conditions during rolling is investigated.Best results are obtained with samples with a wavy interphase, produced under the following cladding parameters: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c} {10^ \circ \le \beta \le 18^ \circ} \\ {1400 \le {\rm v}_{\rm K} \le 2600{{\rm m} \mathord{\left/ {\vphantom {{\rm m} {\rm s}}} \right. \kern-\nulldelimiterspace} {\rm s}}} \\ \end{array} $$\end{document}It is shown, that in comparison with conventional methods explosive cladding has advantages both in processing and quality.

    Description / Table of Contents: Progress in Contact Material Technology. Materials for electrical contacts have to show a plurality of different properties which in most cases cannot be found with pure metals. The development of new and better contact materials is therefore restricted to alloys and mostly to composite materials. The use of intermetallic compounds and ordered alloys will be described. This type of materials shows better corrosion behaviour, lower are erosion and lower material transfer.Silver-, gold- and platinumbased dispersion hardened alloys and methods of manufacture will be described. Today there are tendencies for the use of fiber reinforced metals as materials for electrical contacts. Some applications will be discussed.
    Notes: Werkstoffe für elektrische Kontakte müssen eine Vielzahl verschiedener Eigenschaften aufweisen, die im allgemeinen bei reinen Metallen nicht gefunden werden. Die Entwicklung neuer bzw. verbesserter Kontaktwerkstoffe ist daher auf Legierungen, in erster Linie jedoch auf Verbundwerkstoffe beschränkt. Es wird über die Verwendung von intermetallischen Verbindungen und geordneten Legierungen berichtet, die sich gegenüber üblichen Legierungen durch besseres Korrosionsverhalten, geringeren Abbrand und geringere Materialwanderung auszeichnen. Dispersionsverbundwerkstoffe auf Silber-, Gold- und Platinbasis und neue Herstellungsverfahren werden beschrieben. Mit Hilfe der Faserverbundtechnik können günstige Eigenschaftskombinationen erreicht werden.

    Description / Table of Contents: Ultrasonic Welding of Contact Materials.Ultrasonic welding of metals has found only a few industrial applications until now. Today however ultrasonic welding equipments with high power output for the welding of thicker parts are available. Contact materials have been welded ultrasonically on various base materials, e. g. silver and silver alloys on copper and copper alloys and aluminium. Bond quality was determined by shearing off the contact plates from the base material. Metallographic investigations and microhardness measurements were made to examine the bonding mechanisme. Ultrasonic welding will be a very good supplementary method in contact technology mainly for the welding of hardly weldable components like AgCdO or Al.
    Notes: Das Ultraschallschweißen als Verfahren zum Verbinden von Metallen hat sich bis heute nur auf wenigen Gebieten der Technik durchgesetzt. Inzwischen stehen jedoch Geräte mit hoher Leistung zur Verfügung, mit denen auch relativ dicke Teile verschweißt werden können. Es wurde versucht, das Ultraschallschweißverfahren zur Befestigung von Kontaktwerkstoffen auf Trägerwerkstoffen zu verwenden. Dazu wurden Silber und Silberlegierungen auf Träger aus Kupfer und Kupferlegierungen sowie Aluminium mit Ultraschall aufgeschweißt. Die Haftung wurde im Abscherversuch ermittelt. Metallographische Untersuchungen und Mikrohärtemessungen sollten Aufschluß über die Bindungsverhältnisse in der Ultraschallschweißnaht geben. Das Ultraschallschweißen kann die herkömmlichen Schweißverfahren der Kontakttechnik vor allem bei schwer schweißbaren Werkstoffen wie z. B. AgCdO, Al etc. wirkungsvoll ergänzen.
