研究了AZ80镁合金高温变形织构的形成机制。从具有(0001)织构的轧制板材中加工出三种不同初始织构的试件。平面应变压缩试验在723K，5.0×10(-2)S(-1)应变范围内进行，应变范围为-0.4~-1.0。无论初始织构如何，(0001)(10(1)over bar0)组分的发展都得到确认。结果表明，(0001)<；10(1)相的发展可归因于变形过程中晶界的迁移。除了(0001)(1010)组分外，还根据初始纹理出现了几个纹理组分。
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 x 10(-2)s(-1) and strains ranging from -0.4 to -1.0. Development of (0001)(10 (1) over bar0) component is confirmed regardless of the initial texture. It is concluded that the development of (0001) < 10 (1) over bar0 > component can be attributed to the grain boundary migration during deformation. Besides (0001)(1010) component, several texture components appeared depending on the initial texture.
