通过差示扫描量热技术 ,研究了热循环对 Cu- 2 3.6 Zn- 4 .4 7Al- 0 .2 3Mn- 0 .17Ni形状记忆合金中双可逆相变的影响。结果表明 ,X→ M转变温度随热循环的进行而降低 ,而马氏体逆转变的温度几乎不发生变化。
The effect of thermal cycling on the reversible phase transformation in Cu-2 3.6 Zn- 4 .4Al-0.2Mn-0.1Ni0.7Ni shape memory alloys was studied by differential scanning calorimetry. The results show that the transformation temperature of X → M decreases with the progress of thermal cycling, while the temperature of martensitic transformation almost does not change.
