Paper Title:
Research on Hot Upsetting Deformation Behavior and Dynamic Recrystallization for AZ31
  Abstract

The AZ31 Mg alloy was upseted from 250°C to 500°C. In optical microscopy, as the temperature increases, the volume fraction of deformation twin will reduce to a minium and vanish. Simultaneously, some small dynamically recrystallized grains were observed at the boundaries of origin grains and twins. When temperatures rise from 350°C to 500°C , the volume fraction and size of DRX grains increases .By the compression test of the upsetting proof samples, the compressive strength reach a maxium, and reduce during further rising temperatures.
