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

      摘要
    • 摘要: 借助Gleeble-1500D型热模拟试验机,研究了锑和混合稀土对AZ31镁合金在不同温度下(260～420 ℃)的热压缩流变应力和动态再结晶的影响.结果表明：AZ31镁合金的变形抗力随变形温度的升高逐渐减小;分别加入质量分数为1%RE和1%Sb后,其变形抗力显著增大,同时有效促进了热变形过程中的动态再结晶.

       

      Abstract: 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.
