摘要
本文对多晶 Cu-Al-Ni 形状记忆合金进行了力学行为和应力诱发相变的研究。测定了在各种循环下的应力-应变曲线并进行了比较。x-射线衍射结果表明,在低于 Ms 点和高于 A_f 点变形时,分别发生了β_1→γ_1′和β_1→β_1′的诱发相变,并伴有β_1′马氏体的再取向。
The mechanical behaviour in the polystalline sta- te of Cu-Al-Ni alloy has been studied.The stress- strain curves under different cyclings were measured and compared,The result of X-ray diffraction is shown that the main induced phase transformation is β_1→β_1′and β_1→β_1′accompanying the reorientation of β_1′martensite,at the temperatures below Ms and Af separately.
