摘 要: 加热速度对冷变形金属的再结晶织构具有很大影响。利用激光超快速加热方法对冷轧Cu-30%Zn合金进行了再结晶处理。实验结果表明,其织构转变过程与普通加热时差别很大。对于冷轧70%和85%的样品,完全再结晶时的织构均很漫散,伴随着再结晶晶粒长大,两种样品中的织构特征仍然保持漫散趋势。

Abstract:Heating rates greatly affect the recrystallization textures of cold-deformed metals. The laser heating technique was applied to the ultra-rapid annealing of cold-rolled Cu-30%Zn alloy. The experimental results showed that the texture development differs from those observed in conventional annealing; when primary recrystallization completes, the grain orientation distribution is nearly random for the rolled Cu-30%Zn alloy with 70% and 85% reductions; with the continuous grain growth for two groups of the samples, the dispersion character of the grain orientation is still remained.
