Abstract: The shape memory effect （SME） of Fe-30Mn-6Si-4Cr-5Ni alloy was studied.The influences of solid solution temperature,pre-strain and the recovery annealing temperature on the SME of the alloy were investigated. The experimental results show that the platy specimens are in a stress state of tri-axial load due to the influence of Poisson ratio when being tensioned,so that the martensiteare formed in muti-orientations in the course of stress-induced transformation.When the pre-strain is1%, its shape recovery ratio is around 80%; the optimal solid solution temperature is 850oC; and the optimal recovery temperature （600oC） is determined by experiments.
