The specimens of Fe-30 Ni (wt. %) alloy were subjected to deformation-induced martensitic transformation. Thermo-mechanical treatment resulted in the formation of a composite-like microstructure in which the martensite is the strengthening phase. Rolling at temperature of austenite transformation start (AS) leads to deformation-induced α → γ reversed transformation. The achieved austenite exhibits a high density of defects, which influences strength and plasticity of Fe-30 Ni alloy.
