摘要
采用差示扫描量热分析技术在超低降温速率下 ,研究了 Cu Zn Al Mn Ni形状记忆合金的马氏体相变热容 .通过计算 ,该合金由母相向马氏体转变时的最大热容和最大比热容分别是 43.8m J/ K和 574.1 m J/ g· K,其平均热容和平均比热容分别是 1 2 .63m J/ K和 1 65.48m J/ g·K.
The heat capacity during martensite transformation in CuZnAlMnNi shape memory alloy at ultra low falling speed of temperature is studied by using the technology of differential scanning calorimetry. The calculated result shows that the biggest heat capacity and specific heat capacity of the alloy from mother phase to martensite are 43.8 mJ/K and 574.1 mJ/g·K respectively ,and the average value of them is 12.63 mJ/K and 165.48 mJ/g·K respectively.
