本文论述了利用工业纯金属来制备Cu—Zn—Al形状记忆合金。研究了该合金的热弹性马氏体以及可逆形状记忆效应。薄片试样在25℃和70℃之间热循环时,能反复地自动变弯和伸直,经1000次热循环,其偏转角几乎不变,而且,在某一温度范围内,对温度很敏感。表明该合金适于作热敏元件。 This article discusses the use of industrial pure metal to prepare Cu-Zn-Al shape memory alloys. The thermoelastic martensite and reversible shape memory effect of the alloy were studied. The thin specimen can be automatically bent and straightened repeatedly after being thermally cycled between 25 ° C and 70 ° C. After 1000 thermal cycles, the deflection angle is almost constant. Moreover, in a certain temperature range, the temperature is very high sensitive. This shows that the alloy is suitable as a thermal element.
