利用DSC可以快速的测量NiTi形状记忆合金的相转变温度,可以通过相转变温度来对材料进行质量控制。结果表明NiTi形状记忆合金在降温时出现马氏体相变,升温时出现奥氏体相变,实验中记录马氏体起始温度Ms,马氏体结束温度Mf,奥氏体起始温As和奥氏体结束温度Af,并对相变过程进行了讨论。 DSC can be used to quickly measure the phase transition temperature of NiTi shape memory alloys, and the quality of the material can be controlled by the phase transition temperature. The results show that martensitic transformation occurs in NiTi shape memory alloy during cooling and austenite phase transformation occurs at elevated temperature. In the experiment, the initial temperature of martensite Ms, the end temperature of martensite Mf, the initial temperature of austenite As And austenite finish temperature Af, and the phase transition process is discussed.
