Deformed texture of copper processed by equal channel angular pressing via different angle routes WU Bao-lin(武保林)1, HUANG Zhen-wei(黄震威)1, ZHANG Yu-dong(张宇东)1, 2, BAO Lei(宝 磊)1 , C. ESLING2 1... is corresponded with that of rolling deformation modes. Cold-deformed texture was investigated. The results show that the texture character in pure copper processed by ECAP is related with intersection angle (F......

structures. Prism pattern, which is used in many optical applications, was selected as a model pattern. The prism pattern is 50 ?m in pitch and 108° in the vertical angle. The overall size... in the cavity were measured at different positions in the cavity and the replication of the pattern was also measured at the same positions. The results show that the pressure or temperature profile through......
