Abstract

The effect of Co addition to an Fe-13%Cr-5%Mo-10. 5Ni alloy on the strain-induced transformation was studied. All the alloys used have metastable austenitic structure after air cooling from a solution treatment temperature 1223 K, and transform to martensite during deformation at room temperature. By the addition of Co, Md temperature decreases by 8. 4 K per 1% Co, and also the martensite morphology changes from lath to platelet. The TRIP phenomenon of Fe-13%Cr-5%Mo-Ni-Co alloys with the mixed structure of age-hardened martensite and metastable austenite was also studied.
