Influence of Annealing on Microstructure and Texture of AZ31 Magnesium Alloy Sheet

Article Preview

Abstract:

There are strong basal textures in AZ31 magnesium alloy sheet. Through rolling and post-annealing, we can significantly reduce the basal texture, and with the rising of deformation, the texture intensity falls. The peak intensity of basal texture reduced from 12 to 4 when the rolling deformation rises to 35%. The influence of post-annealing on grain refinement is very obvious. When the temperature of pre-annealing is 773K and rolling temperature is 623K, the grain size reduce to 201μm after 1% deformation. But we can reduce the grain size to 30μm after post-annealing. If the rolling deformation is 36.4%, the grain size reduces to 73μm. But after post-annealing, the grain size reduces to 12μm.
