Rapid solidification has a potential for improving perfomance in the fusion environment (first-wall materials, limiters, superconductors, ...) through structural refinements of crystalline materials and the preparation of amorphous materials with selected compositions. Compaction techniques which are used for rapidly solidified particulates allow as well for preparation of graded or layered materials. The following topics are being studied by using rapid solidification under a current M.I.T. alloy devlopment program: swelling resistance and high temperature strength of austenitic stainless steels; DBTT and high-temperature strength of ferritic steels; high strength copper alloys; simulation techniques (boron, lithium doping); irradiation damage in metallic glasses at high fluences.
