Abstract

This study investigated the distribution variations of the 0002 poles of magnesium after experienced a series of numbers of equal-channel angular pressing (ECAP) passes through either the Bc route or the C route. For the ECAP processing, the mold channel angle was 142° and the sample temperature was 200 °C. The results show that most 0002 poles are in the ring of about 60–80° away from the ED for all ECAPed samples, and the location of the maximum intensity oscillates in the 60–80° range. The first ECAP pass increased the nonuniformity of the distribution of 0002 poles, while the following ECAP passes resulted in more uniform distribution of 0002 poles in the 60–80° ring and reduced texture intensity through decreasing the maximum intensity and the intensity range of 0002 poles with the increase in the number of ECAP passes for both Bc and C routes.
