实验发现，高静水压使近化学计量比的Ni2MnGa单晶的预马氏体相变温度向低温方向移动，其速率约为−6K/Gpa。计算了伴随这一转变的体积效应值和预马氏体相变温度与马氏体相变温度合并的临界压力。
It is found experimentally that a high hydrostatic pressure shifts the temperature of premartensitic transition in the near stoichiometric Ni2MnGa single crystal toward low temperatures with a rate of about −6K/GPa. The values of volume effect accompanying this transition and the critical pressure for merging of the temperatures of premartensitic and martensitic transitions are evaluated.
