研究了采用放电等离子烧结法获得的Ni-Mn-Ga合金的马氏体相变、力学性能和磁场诱导应变。结果表明，烧结试样的马氏体转变与常规大块合金基本相似。与传统熔炼技术获得的样品相比，烧结 Ni-Mn-Ga 合金的延展性显着增强。据报道，这是迄今为止最高的断裂应变。此外，首次研究了烧结 Ni-Mn-Ga 合金中的磁场诱发应变。 (C) 2011 Elsevier B.V. 保留所有权利。
Martensitic transformation, mechanical property and magnetic-field-induced strain of Ni-Mn-Ga alloys obtained using the spark plasma sintering method have been investigated. The results show that the martensitic transformation of the sintered specimen is basically similar to that of conventional bulk alloys. The ductility of sintered Ni-Mn-Ga alloys is significantly enhanced compared to the specimen obtained by conventional melting technique. The highest fracture strain so far is reported. Moreover, magnetic-filed-induced strain in sintered Ni-Mn-Ga alloys has been studied for the first time. (C) 2011 Elsevier B.V. All rights reserved.
