The present paper deals with the three systems FeNi, FeCo and FeMn. Specimens containing 50 to 400 at. p.p.m. of solute has been electron irradiated together with pure iron. The production and the recovery of the radiation-induced defects have been studied throughout stage I and stage II (up to 200K). The experimental results are interpreted as follows. The three solutes Ni, Co and Mn act as traps for the iron self-interstitial during its free migration in stage IE around 130K. A mixed interstitial is formed with these three solutes, which migrate just above stage IE (Fe-Ni) or in IE temperature range (Fe-Co, Fe-Mn), by the same mechanism as the self-interstitial in IE, thus resulting in solute long-range diffusion below stage III (vacancy migration). The present results are compared with previous ones from the literature.
