The extensive use of austenitic Fe-Cr-Ni alloys in cryogenic engineering and space investigations necessitates the study of the strength and plastic properties of these materials at low temperatures. One of the most important properties of metastable stainless Fe-Cr-Ni alloys is the martensitic transformation, which occurs in them at low temperatures and during deformation. During this process, the initial fcc (y) austenite rearranges into paramagnetic hcp (E) martensite and ferromagnetic bcc (a) martensite. Whether martensitic transformation or another process is dominant depends on the chemical composition, temperature, and degree of deformation of the alloy.
