经一定热处理和应变后的Cu-Zn-Al合金具有良好的双程形状记忆效应,有希望在工业上获得应用,研究了多次热循环及在不同温度时效对Ms温度和形状回复性能的影响。经700次热循环后的双程形状回复率仍高达60％左右,高温时效使双程形状回复率衰退很快,但在100℃以下时效则对双程形状回复性能影响不大。
The Cu-Zn-Al alloy after a certain heat treatment and strain has a good two-way shape memory effect and is expected to be used in industry. The effects of multiple thermal cycles and aging at different temperatures on the temperature and shape recovery of Ms . After 700 thermal cycles, the recovery rate of the two-way shape is still as high as 60%. The high temperature aging causes the decline of the two-way shape recovery rate to decline rapidly. However, aging below 100 ° C has little effect on the two-way shape recovery performance.
