摘要
原始取向为{001}(uv0)的柱状晶Al样品分别冷轧到10％,30％和50％,采用EBSP技术定量表征了不同取向晶粒的宏观分裂,结果表明,不同取向晶粒在轧制过程中的分裂模式不同.利用位错滑移模型合理地解释了观察到的宏观分裂时的晶体转动.
Columnar grain Al samples with {001}{uv0} orientations were cold rolled to reductions of 10%, 30% and 50%, respectively. The macroscopic subdivision of grains with different orientations was characterized in detail by using EBSP technique. It is found that the macroscopic subdivision patterns of different oriented grains are different. A model based on dislocation slip was used to analyze the observed macroscopic subdivision patterns.
