超高纯铝在动态塑性变形过程中的微观组织演化

摘要

Ultra-high purity aluminum was deformed by dynamic plastic deformation( DPD) method to reductions of 5% 、13%、21% ,rnand 75% , respectively. The microstructure evolution in the processing was investigated by using EBSD and optical microscopyrntechnique.%利用金相显微镜和EBSD技术对超高纯铝(99.999％)在动态塑性变形(dynamic plastic deformation,DPD)过程中的微观组织及取向差进行了表征,分析了超高纯铝在DPD变形方式下组织的演变规律.
