摘要
本文对多晶Cu-Al-Ni形状记忆合金进行了应力诱发相变的研究。试验是在低于Ms和高于Af温度下采用X-射线衍射的方法进行的。结果表明,在稍低于Ms点和稍高于Af点时分别发生了β_1→γ′_1和β→1β′_1的诱发相变,并伴随有β′_1马氏体的再取向。
A study has been made of the induced phase transformation under the stress in the polycrystalline state of Cu-Al-Ni alloy. Experiments was carried out by means of the x-ray diffraction at temperatures below Ms and above Af. Itis shown that the induced phase transformation is mainly β1→γ'1 and β1→β'1to accompany the reorientation of β'1 martensite at temperatures slightly below Ms and above Af separately.
