摘 要: 加熱速度對冷變形金屬的再結(jié)晶織構(gòu)具有很大影響。利用激光超快速加熱方法對冷軋Cu-30%Zn合金進行了再結(jié)晶處理。實驗結(jié)果表明，其織構(gòu)轉(zhuǎn)變過程與普通加熱時差別很大。對于冷軋70%和85%的樣品，完全再結(jié)晶時的織構(gòu)均很漫散，伴隨著再結(jié)晶晶粒長大，兩種樣品中的織構(gòu)特征仍然保持漫散趨勢。

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.
Key words: laser heating; Cu-30%Zn alloy; recrystallization texture
