研究了热制动对NiCoMnSn形状记忆合金L2（1）-四元马氏体相变的影响。在差示扫描量热分析中，通过中断加热/冷却来研究该现象。实验结果表明，在M-s和M-f之间的冷却停止期间，马氏体正向相变继续完成。同样的行为也被观察到的逆相变加热。这些观察结果表明，在有限的冷却速率下，Ni_（43）Co_（7 Mn）Sn_（41）Sn_9合金中的L_2（1）-四方马氏体相变是时间依赖的。(C)2009爱思唯尔有限公司保留所有权利。
Effect of thermal arrest on the L2(1)-tetragonal martensitic transformation in a NiCoMnSn shape memory alloy was investigated. The phenomenon was studied by interrupted heating/cooling in differential scanning calorimetry analysis. The experimental evidence indicates that the forward martensitic transformation continued to completion during cooling arrest between M-s and M-f. The same behavior was also observed for the reverse transformation on heating. These observations demonstrate that the L2(1)-tetragonal martensitic transformation in the Ni43Co7Mn41Sn9 alloy is time dependent at the finite cooling rate. (C) 2009 Elsevier Ltd.
