Deformation and Texture Behaviors of Al-3mass%Mg Alloy at High Temperatures

Uniaxial compression tests were conducted on Al-3mass%Mg alloy under various temperatures and true strain rates. High temperature yielding was observed at the temperatures higher than 623K. Texture examination elucidated that fiber textures are constructed in all the deformation conditions examined in this study. It was found that the kinds and the intensities of texture components varied depending on deformation temperature, strain rate and the amount of strain.

It was concluded that orientation stability against the lattice rotation by slip deformation as well as the rapid recovery during the deformation of the grains close to {001} orientation made it possible to grow by consuming the other deformed grains with the orientations such as {011}, resulting in the development of {001} texture.
