本文用磁化强度和电阻率测量方法研究了Mn_（50）Ni_（40）In_（10）薄带的正、逆马氏体相变。该合金为L21型单相奥氏体，其转变为14M单斜马氏体。马氏体相变伴随着电阻率的大变化。特征转变温度的字段依赖性的报告。观察到了具有大滞后损耗的场致逆马氏体相变。还报道了在直接马氏体相变发生的温度区间内磁化等温线的可逆性。
Direct and reverse martensitic transformations have been studied in Mn50Ni40In10 ribbons by means of magnetization and electrical resistivity measurements. The alloy is L21-type single-phase austenite, which transforms into a 14M monoclinic martensite. The martensitic transformation is accompanied by a large change in the electrical resistivity. The field dependence of characteristic transformation temperatures is reported. A field-induced reverse martensitic transformation with large hysteretic losses was observed. The reversibility of magnetization isotherms in the temperature interval where direct martensitic transformation occurs is also reported.
