Notes:
Commercially Pure Magnesium initially hot rolled and having a basal texture wasdeformed by Equal Channel Angular Extrusion (ECAE). ECAE was carried out upto 8 passes in a90° die following routes A and Bc through a processing sequence involving two temperatures,namely 523 and 473 K. Texture and microstructure formed were studied using electron back scatterdiffraction (EBSD) technique. In addition to significant reduction in grain size, strong 〈0002〉 fibertexture inclined at an angle ~ 45o from the extrusion axis formed in the material. Texture was alsoanalyzed by orientation distribution function (ODF) and compared vis-à-vis shear texture. Asignificant amount of dynamic recrystallization occurred during ECAE, which apparently did notinfluence texture
