研究了添加硼对(Ni54Mn25Ga21)(100-x)B-x合金的显微组织、相变温度、力学性能和形状记忆效应的影响。结果表明，当x=0时，马氏体相变开始温度M-S从465K单调下降到x=3时的278K。(Ni54Mn25Ga21)(99.5)B-0.5合金的压缩断裂应变为22.3%，可逆应变为6.8%。(C)2015爱思唯尔有限公司。保留所有权利。
The effects of boron addition on the microstructure, transformation temperature, mechanical properties and shape memory effect of (Ni54Mn25Ga21)(100-x)B-x alloys were investigated. The results showed that the martensitic transformation start temperatures M-s decreased monotonically from 465 K for x = 0-278 K for x = 3. Boron addition refined the grain and significantly enhanced the mechanical properties. The compressive fracture strain of 22.3% and reversible strain of 6.8% were obtained in (Ni54Mn25Ga21)(99.5)B-0.5 alloy. (C) 2015 Elsevier Ltd. All rights reserved.
