采用C路线等道角挤压四道次，使0.15% C的商用钢承受了~ 4的应变。仔细的显微组织检查表明，在当前等道角挤压条件下，晶粒细化在第一道次最为显著。随后的道次也产生了相当大的晶粒细化，最终晶粒尺寸约为0.3 μm。高角边界部分随时间的增加而逐渐增加
The commercial 0.15% C steel was subjected to a strain of∼ 4 by utilizing equal-channel angular pressing of four passes with route C. The careful microstructural examination revealed that, under the present equal-channel angular pressing conditions, grain refinement was the most significant at the first pass. The subsequent passes also resulted in considerable grain refinement showing the final grain size of about 0.3 μm. In addition, a portion of high angle boundary increased progressively with
