Abstract
Magnesium sheet materials AZ31, AM50, ZM21, ZK10, and ZK30 were tested to failure at 450C at a strain rate of 0.001/s. Each of these materials exhibit significant changes in grain structure during deformation, especially in the necked regions of the failed samples. Grain size in the neck is shown to vary with thickness strain and strain rate. Some materials exhibit significant coarsening along the necked region while others show very little change. The results of this work can be used to help validate models for dynamic recrystallization in magnesium.
