In order to further improve shape memory effect(SME) and process efficiency of a FeMnSiCrNiNbC alloy , the effects of different electropulsing treatment on microstructure and SME of the alloy were investigated in the paper. The results showed that the shape recovery ratio of specimen subjected to 10% tensile pre-deformation following electropulsing treatment at 300V and 1Hz for 11 times reached maximum 86.5%, 8.1% greater than that subjected to ageing at 800℃ for 15 minutes after 10% tensile pre-deformation. In addition, it was found by SEM and TEM analysis that NbC carbides induced by electropulsing treatment precipitated more quickly, and the amount of NbC was much more and the size of NbC particle was smaller. Therefore, its SME can be further improved and the process efficiency is higher.
