Abstract

The formation behavior of textures during high temperature plane strain compression deformation is experimentally studied on AZ80 magnesium alloy. Three kinds of specimens with different initial textures are prepared from the extruded bars having a <10\bar{1}0> fiber texture. Plane strain compression is conducted at 723 K, 5.0 × 10−2 s−1 and strains ranging from −0.4 to −1.0. New grains appeared after the deformation up to −0.4 in true strain. Initial texture gradually changes with increasing strain. After the deformation up to −1.0 in true strain, (0001)<10\bar{1}0>, {11\bar{2}0}<10\bar{1}0>, (0001)<11\bar{2}0> and {10\bar{1}0}<0001> appeared depending on the initial texture. (0001)<10\bar{1}0> and {11\bar{2}0}<10\bar{1}0> are formed irrespective of the initial texture. Simple crystallographic examination showed that all the texture components are orientations stable for the plane strain compression.
