The effect of amount of deformation on the martensitic transformation and shape memory effect in a Fe-16Mn-5Si-9Cr-4Ni alloy is studied. It is found that both ε- and α'- martensite are induced by deformation. With increasing amount of deformation, γ→ε→α' transformation is greatly enhanced. the highest shape memory strain 3.8% is reached when the amount of deformation is about 5%.
