Texture Formation in AZ91 Magnesium Alloy during High-Temperature Uniaxial Compression

Abstract

Texture development in Magnesium alloy AZ91 having a weak (0001) texture before deformation is studied by uniaxial compression tests at 673K and 723K, strain rates ranging from 5.0×10-4s-1 to 5.0×10-2s-1 up to a strain of -1.0. The fiber texture is formed in all of the deformation conditions. The main component of the texture varies depending on deformation conditions. The position of maximum axis density varies depending on final stress. It is concluded that the (0001) fiber texture develops by continuous dynamic recrystallization.
