块体超细晶(晶粒尺寸1~1000nm)材料具有优异的物理和力学性能,是材料领域研究的热点之一.超细晶材料的力学行为显著不同于常规材料,建立大应变变形超细晶材料的包含软化行为的应力应变关系方程具有重要意义.本文采用等通道变形（ECAP）工艺,对高层错能金属高纯铝（9 9.999%）沿BC路径进行1,2,4,8,12,16,24道次挤压变形.通过对不同ECAP道次试样进行了拉伸与压缩测试,观察了金相显微组织,XRD和TEM测试分析了微观组织

翻译?汉字也要翻译?
Block ultra-fine grain (grain size of 1 1000nm) materials have excellent physical and mechanical properties of materials is one of the hot areas of research.Ultra-fine grain material mechanical behavior significantly different from conventional materials,establish a contingency deformation of the ultra-fine grain materials include softening of the stress and strain relations between the equation is of great significance.In this paper,such as access deformation (ECAP) technology,can be wrong for senior high aluminum metal (99.999%) along the path to 1,2,4,8,12,16,24 BC Road,squeezing deformation.Through the different sample ECAP Road,a tensile and compression tests,observation of the microstructure microstructure,XRD and TEM analysis of the test microstructure
