研究酸洗去除Ｎｉ—Ｔｉ形状记忆合金氧化皮过程中氢渗入基体对材料力学性能的影响，通过扩散退火处理可改善Ｎｉ—Ｔｉ合金的韧性和塑性指标，恢复优良的力学性能，并对原因进行分析。
The effect of hydrogen infiltration into the matrix on the mechanical properties of the Ni-Ti shape memory alloy was studied during acid pickling. The ductility and plasticity index of the Ni-Ti alloy can be improved by diffusion annealing, and the excellent mechanical properties were restored. analysis.
