摘要
讨论了形状记忆合金相变温度的常用测量方法的现状、优缺点及发展趋势,包括变温X射线法、热分析法、膨胀法、声发射法及电阻法.其中电阻法精度高,电路简单,测量过程对试样的影响小,速度快,被广泛采用.
The status qu, o, their merits and shortcomings, and the future trends of the commonly used methods of measuring Shape Memory Alloys' transformation temperature are reviewed. The methods concerned include X-ray diffraction, thermal analysis, dilatometry, acoustic emission and electrical resistance, of which the last one is widely used in that, in addition to the fact that the testing process can hardly affect the samples, it has high precision, simple electrocircuits, and high speed as well.
