In order to further enhance shape memory effect (SME) and improve treatment process in Fe-based shape memory alloys, a pre-deformed Fe-Mn-Si-Cr-Ni-Nb-C alloy was subjected to a electropulsing treatment. The results show that the shape memory ratio reached the maximum 80% for the specimen subjected to a 5% pre-deformation and the electropulsing treatment at 300 V and 1 Hz for 13 times, which is 12% greater than that subjected to an ageing at 800 ℃ for 1000 s. In addition, it is found by SEM observation that the electropulsing treatment can induce a large amount of NbC precipitates with small sizes in the bulk at a short time, therefore, improve the shape memory property and increase the efficiency of shape memory effect efficiently.
