Effect of Antimony and Rare Earth on Hot Deformation Behavior of AZ31 Magnesium Alloy

The effect of antimony and rare earth on the flow stress and dynngzhou amic recrystallization of AZ31 magnesium alloy at different temperature (260-420 ℃) was investigated by hot compression testing on a Gleeble-1500D thermal simulator.The results have indicated that the resistance of deformation is decreased by the elevation of deformation temperature;at the same temperature,the additions of 1%RE and 1%Sb to the AZ31 magnesium could effectively improve the resistance obviously and accelerate the dynamical recrystalization.
