For a tested alloy containing 0.16 wt% RE, the shape recovery rate achieves 80% in water-quenched state and almost 100% after two cycles of training with a 4% prestrain. However, further more amount of RE addition may cause the formation of coarse, irregularly shaped and inhomogeneously distributed second phase particles in the alloys, resulting in a dramatic degradation in SME.

结果表明：在Fe-25Mn-6Si-5Cr合金中加入微量的稀土元素（0.032-0.20wt％）可以显著改善合金的形状记忆效应：特别是稀土含量为0.16wt％时，在预拉伸为4％的情况下，水淬状态下其恢复率可达80％，经两次训练后形状恢复率可接近100％。
