实验研究了单晶铁磁形状记忆合金Ni49.4Mn27.7Ga22.9在马氏体-马氏体相变过程中复杂的温度-时间演化的超弹性应力-应变环。基于马氏体形核事件的统计描述的相变行为的模型的开发和用于压缩试验中的实验数据的理论描述和分析。
The superelastic stress–strain loops indicating complex temperature–time evolution of the single crystalline ferromagnetic shape memory Ni49.4Mn27.7Ga22.9alloy which undergoes the austenite–martensite transformation (MT) have been experimentally studied. A model of transformation behaviour based on the statistical description of martensite nucleation events is developed and used for the theoretical description and analysis of experimental data in compression tests.
