Abstract
Deformation twinning in f.o.c. crystals has been investigated by vising silver-and copper-alloy crystals, which were deformed in tension at temperatures down to 4·2°K. Problems mainly concerned are (1) the nucleation process with particular relation to cross-slip and (2) the suppression of the growth of twins in high-concentration alloys. First, a postulate previously made that twinning is nucleated as a stress-relief process complementary to cross-slip has been confirmed. Second, the suppression of the twin growth in high-concentration alloys has been interpreted in terms of the interaction of twinning dislocations with dislocations of the critical system abundantly induced by the Lüders deformation.Keywords
