摘　　要：Effect of compound rare earth (RE) on shape memory effect (SME) of Fe-Mn-Si-Ni-C shape memory alloy was studied by bent measurement,thermal cycle training, SEM and XRD etc. The results show that metallurgic microstructure is refined and SME improved evidently with the addition of compound RE. The alloy appears little two-way shape memory effect. The former training and addition of compound RE are two effective ways to restrain martensitic stability. XRD analysis also indicates that ε→γ reversible transition ratio increases by training greatly help to improve SME of the alloy.Effect of compound rare earth (RE) on shape memory effect (SME) of Fe-Mn-Si-Ni-C shape memory alloy was studied by bent measurement,thermal cycle training, SEM and XRD etc. The results show that metallurgic microstructure is refined and SME improved evidently with the addition of compound RE.
