摘　　要：为了获得较细的晶粒,采用等通道角挤压(ECAP)变形的方法对5083铝合金按A和B两种方式进行变形;变形后两种样品用背散射电子衍射(EBSD)技术进行测定,获得了极图、反极图、取向差分布、晶粒尺寸等实验结果。结果表明:5083铝合金按A方式晶粒细化效果强于B方式,而B方式织构面积及织构强度都大于A路径。5083 aluminum alloy was successfully processed by equal channel angular pressing （ECAP） with A and Bc way For acquisition better grain refinement. The specimens pressed by two way are characterized by using the electron back scatter diffraction （EBSD）. The results, such as the pole figures, inverse pole figures, misorientation maps, and the grain size are obtained. The results of the experiments show that the grain refinement is better by A than by Bc way, but Bc shows a higher content and texture strength than A way.
