Abstract | The flow stress anomaly in some L12 alloys is a well-documented phenomenon. There are, however, other L12 alloys which show a large and negative temperature dependence of yield strength (TDYS). The present work attempts to answer the question of why materials with the same L12 structure can exhibit different TDYS by investigating the L12 compound Fe3Ge. Transmission electron microscopy studies show that 〈110rrang;{001} are the easiest slip systems in Fe3Ge. The high Peierls stress can readily explain the large and negative TDYS. The absence of the more usual octahedral slip systems is thought to be due to the instability of APBs on {111} planes. © 1992. |
