摘要
Commercially Pure Magnesium initially hot rolled and having a basal texture was deformed by Equal Channel Angular Extrusion (ECAE). ECAE was carried out upto 8 passes in a 90 degrees die following routes A and B-c through a processing sequence involving two temperatures, namely 523 and 473 K. Texture and microstructure formed were studied using electron back scatter diffraction (EBSD) technique. In addition to significant reduction in grain size, strong < 0002 > fiber texture inclined at an angle similar to 45 degrees from the extrusion axis formed in the material. Texture was also analyzed by orientation distribution function (ODF) and compared vis-a-vis shear texture. A significant amount of dynamic recrystallization occurred during ECAE, which apparently did not influence texture.
