PROCESS FOR PRODUCING PLASTICALLY DEFORMED IRON-RHODIUM BASE ALLOY BODIES

摘要

This invention concerns a new process for producing plastically deformed shapes of iron-rhodium base alloys which exhibit controlled magnetic transitions. The process comprises hot and cold reducing a starting body to some final dimension, the cold reduction causing an increase in the ductility of the starting body by partially rendering it crystallographically face-centered cubic, and then heat treating the final body at a temperature no lower than about 235 DEG C. to produce a CsC1-type ordered crystal structure having an abrupt magnetic transition. Subsequent cold reducing of the heat-treated body by varying amounts alters the nature of the magnetic transition.
