Abstract

Elevated temperature 1MeV electron irradiations have been carried out on a series of Fe-Cr alloys (1-10wt. % Cr) and an Fe-10 wt % Mo alloy. Results show that dislocation loop populations are similar in all the Fe-Cr alloys and in the Fe-10Mo alloy, and consist of an approximately equal distribution of a<100> and a/2<l 11> Burgers vector types. Differences in loop morphologies and behaviour may be related to the nature of the solute.
