JAUE2022-131: Effect of Strain Rate on Texture Formation Behavior of AZ80 Magnesium during High Temperature Plane Strain Compression

Abstract

Magnesium alloys are mainly processed at high temperatures from low workability due to limited slip system at room temperature. Since the texture formed during high-temperature machining changes the properties of the material and affects subsequent processing, it is necessary to control. Plane strain compression tests were performed at 723 K, 0.0005 s-1 to investigate the effect of strain rate on texture formation. In the previous study, (0001) basal texture was formed and developed at strain rate of 0.05 s-1 , but in the case of 0.0005 s-1 , it was observed that the texture was formed and developed at about 23 degrees away from (0001). This means that strain rate affects the texture formation behavior of AZ80 magnesium alloy in this study.
