Abstract

In order to establish the prediction method of high temperature deformation behavior, a bcc solution-hardened Fe-3.5 at%Mo alloy was deformed in tension at temperatures from 1050 K to 1150 K along three different paths of constant strain rate and continuously varying strain rate, and it was inspected whether or not the prediction method proposed for fcc solution-hardened Al-Mg alloys could be applied to the deformation behavior of the bcc alloy. It is found that the method can be applied to the bcc alloy with some modification of the parameters used for the prediction, and the limiting conditions of the applicability can be explained by the break away of dislocations from the solute atmosphere in the same way as that for fcc alloys.
