Abstract
A comparison of data on yielding and flow of b.c.c. metals indicates that the proportional limit, the lower yield stress, the friction stress of Hoslop and Petch, and the flow stress after some strain beyond the Lüders strain all exhibit the same strong temperature dependence. This suggests that they all represent the same deformation mechanism. Furthermore, in iron the temperature dependence of these prameters depends on the total interstitial content and on the presence of grain boundaries. One when both are present does one observe the very strong temperature dependence normally associated with commercial irons and steels.Keywords
