摘要
用ＤＳＣ－７研究了ＣｕＺｎＡｌ单向、双向记忆合金的相变潜热，发现：单向、双向记忆合金相变过程的ＤＳＣ曲线形状各异，单向记忆合金的ＤＳＣ曲线为犬牙状，有多个峰；而双向记忆合金的ＤＳＣ曲线只有一个峰。在相变热的大小上，单向记忆合金的相变热比双向记忆合金约大１／４。
One way and two way shape memory alloys of Cu-21% Zn-6% Al (wt-%)were studied by differential scanning calorimetry. The profiles of endothermic and exothermic peaks of one way shape memory alloy are different from those of two way shape memory alloy.The former shows smooth peaks while the other shows bumpy peaks. Besides, the heat of martensitic transformation of two way shape memory alloy is about 25% less than that of one way shape memory alloy.
