Observation of pseudoelasticity in a cold rolled Fe-Ni-Mn martensitic steel

In this research, the reverse transformation of martensite to austenite and pseudoelastic behavior in Fe-10Ni-7Mn (wt%) lath martensitic steel were investigated under different amounts of cold rolling. The results indicated that the transformation of stress-induced austenite to epsilon martensite is responsible for pseudoelastic behavior in 80% cold rolled specimen.
