Since the shape memory effect (SME) in Fe-Mn-Si alloy was observed, much research has been done on this kind of shape memory alloy (SMA) because of its particularly good one-way SME and low cost. With the addition of Cr and Ni, it is possible to reach a good corrosion resistance, which confers to this type of alloy a future use in industry. But compared with TiNi and Cu-based shape memory alloys, the incompleteness of shape recovery and less reversible strain are the main disadvantages of this kind of alloy. Yang et al. reported that the fully reversible strain was less than 2% and only 4.5% of the net reversible strain could be obtained under the prestrain of 8%. In the present work, 3% and 5% of the net reversible strain can be obtained in the case of 6.3% prestrain. The paper is mainly concentrated on the influence of these three elements on the SME of Fe-Mn-Si-Cr-Ni alloys.
