The recrystallization texture in commercially pure Al is investigated after the samples are rolled differently and annealed.The samples with low rol- ling reductions could be generally recovered or recrystallized in situ and characterized by the re- tained G{110}<001>component.This recovery process decreases during annealing with the increase of reduction.The appearance of the B/R{359}. <132>and R{123}<634>components de- pending on the rolling reduction is investigated and the less developed Cube{100}<001>component in commercially pure ahninium is also discussed.

采用两通道夹角Φ=90°,外圆角ψ20°的模具,实现TA1纯钛C方式4道次室温ECAP(Equal Channel Angular Pressing)变形,制备了表面光滑无裂纹的变形试样.研究纯钛室温ECAP变形试样的织构演变特征.结果表明:在ECAP 变形初期,基面织构和锥面织构逐渐向P(ψ1=45°,ψ=0°～90°,ψ2=30°)织构旋转,基面织构和锥面织构减少,柱面织构增加,织构的演变是由位错增殖导致微结构变化引起的.在变形后期因晶粒细化,织构演变主要由整个晶粒的旋转来形成剪切织构,基面织构逐渐增加.

在480～750℃条件下,模拟罩式退火,利用光学显微镜、X射线衍射和金相显微硬度计研究了冷轧Ti-IF超深冲钢晶粒结构的变化,通过取向密度函数分析了再结晶过程织构演变规律.研究表明:冷轧Ti-IF超深冲钢的再结晶温度约为630℃,再结晶过程能够在660℃条件下2h之内完成;冷轧后该钢主要有4种织构,分别是｛001｝〈110〉、｛111｝〈110〉、{111｝〈112〉和{112｝〈110〉;在退火再结晶过程中,{111｝逐渐转变为γ-{111｝,当退火温度升至720℃时,｛001｝〈110〉和{112}〈110〉转变为纤维织构γ-{111｝,最终｛111｝〈110〉和{111｝〈112〉成为主要织构类型.
