Formation of Texture in AZ80 during High Temperature Compression Deformation

Article Preview

Abstract:

Formation behavior of texture during high temperature compression of AZ80 is investigated on the specimens produced from the extruded bar and rolled plate. Special attention is paid on the formation of (0001) (compression plane) texture. Before deformation, (0001) is distributed frequently parallel to the compression plane in the specimen produced from the rolled plates, while (0001) is frequently normal to the compression plane in the specimen produced from the extruded bar. The deformation is performed at temperatures and strain rates ranging from 673K to 723K and 1.0×10-4s-1 to 5.0×10-2s-1, respectively. It is found that fiber textures are formed by the deformation and the main component of the texture varies depending on the deformation conditions. The sharpness of (0001) texture after deformation in the specimen produced from extruded bar is much weaker than that in the specimen produced from rolled plate. It is concluded that the growth of (0001) grains during deformation is the basic process for the (0001) texture evolution.
