AZ80マグネシウム合金の高温変形集合組織の形成に及ぼす初期集合組織の影響

抄録

The texture formation mechanism during high temperature deformation is investigated on AZ80 magnesium alloy. Three kinds of specimens with different initial textures were machined out from rolled plate having a 〈0001〉 texture. Plane strain compression tests were conducted at 723 K, 5.0×10^-2 s^-1 and strains ranging from -0.4 to -1.0. Development of (0001) 〈101‾0〉 component is confirmed regardless of the initial texture. It is concluded that the development of (0001) 〈101‾0〉 component can be attributed to the grain boundary migration during deformation. Besides (0001) 〈101‾0〉 component, several texture components appeared depending on the initial texture.
