The neutron-induced swelling of simple Fe-Cr-Ni, Fe-Mn and Fe-Cr-Mn alloys without solute additions has been studied using fast reactor irradiation in the range 400 to 650/sup 0/C. It appears that in this temperature range these alloys all eventually swell at approx.1%/dpa after the completion of a transient regime. Although the swelling rate of the post-transient regime is remarkably insensitive to composition and irradiation temperature, the duration of the transient regime is sensitive to these variables. Alloys containing manganese instead of nickel show a much lesser sensitivity to composition and temperature, however. Comparison of these results with those of charged particle simulation studies shows that ion irradiation studies can be somewhat misleading when applied to alloy development and optimization. There does not appear to be any potential for development of an iron-based austenitic alloy optimized for swelling resistance as a consequence of a reduced post-transient swelling rate. Any optimized alloy must be based on attempts to extend the transient regime of swelling. 38 refs., 21 figs., 2 tabs.
