Description
The present work deals with the plastic behaviour of polycrystalline vanadium from the onset of plastic deformation to the upper yield point. The stress-strain relation was found to be omega approximately epsilonsub(p)sup(1/2). The influence of the grain size on stress followed a omega approximately d-1 relationship. The initial yield stress was independent of grain size. By means of optical and electron microscopy it was found, that the first dislocation movement starts at grain boundaries. (orig.)
Abstract (German)
In der vorliegenden Arbeit wurde das plastische Verhalten vielkristallinen Vanadiums im Bereich bis zur oberen Fluessgrenze untersucht. Als Spannung-Dehnung-Zusammenhang ergab sich eine omega ungefaehr epsilonsub(p)sup(1/2)-Abhaengigkeit, der Einfluss der Korngroesse konnte durch omega ungefaehr d-1 beschrieben werden. Die Spannung des Gleitbeginns erwies sich als korngroessenunabhaengig. Licht- und elektronenoptische Befunde ergaben, dass die erste Versetzungsbewegung von den Korngrenzen ausgeht.
