Abstract

Copper single crystals and polycrystalline very-low-carbon steel (0.036 wt.% C) were fatigue loaded at low and very low amplitudes. The resulting dislocation structures and surface features were studied and the results correlated. Similarities of the face- and body-centred cubic materials as to the resulting dislocation and surface structures are outlined. In addition, the question of an eventual effect of the loading frequency on the resulting microstructural changes is shortly discussed.

Abstract

Kupfereinkristalle und polykristalliner Stahl mit sehr niederem Kohlenstoffgehalt (0.036 Gew.%) wurden bei kleinen und sehr kleinen Amplituden ermüdet. Die resultierenden Versetzungsstrukturen und Oberflächenerscheinungen wurden untersucht und korreliert. Auch wurden die Ähnlichkeiten der beiden kubisch-flächenzentrierten bzw. kubischraumzentrierter Werkstoffe hinsichtlich Versetzungs- und Oberflächenstruktur ermittelt. Zusätzlich wird die Frage eines eventuellen Einflusses der Belastungsfrequenz auf die resultierenden Mikrostrukturänderungen kurz diskutiert.


Dedicated to Professor Dr. Haël Mughrabi on the occasion of his 65th birthday

Prof. Dr. Stefanie Stanzl-Tschegg Institute of Meteorology and Physics University of Agricultural Sciences Türkenschanzstr. 18, A-1180 Vienna, Austria Tel.: +43 1 470 58 20 13 Fax: +43 1 470 58 20 60

The TEM micrographs of the Cu single crystals were taken by Dr. L. Buchinger within a cooperation with Prof. C. Laird. The author wants to thank both of them for this cooperation.
