摘要
The shape memory effect and recovery ratio of dual-phase Ni(58)Mn(25)G(16.9)Gd(0.1) alloy were investigated by bend test. The results show that this alloy exhibits good shape recovery capability. The recovery ratio of 86% is obtained with bend pre-strain of 4.6% after heating, which is larger than that of other reported dual-phase Ni-Mn-Ga alloys. This characteristic is attributed to the critical slip stress increasing of gamma phase by small amount of Gd addition, improving the ability of gamma phase to resist irreversible deformation.
