研究发现,所开发的Mg—Zn-Mn新型变形镁合金可实现在310℃下的挤压成型,并在该温度下发生了完全的动态再结晶。固溶及时效处理,特别是双级时效处理,能够显著提高该合金的强度,其最高强度达到高强变形镁合金ZK60的强度水平。
It was found that the new Mg-Zn-Mn wrought magnesium alloy could be extruded at 310℃ while complete dynamic recrystallization took place during extruding. Solution and aging treatment, especially 2-step aging, can significantly increase the strength of the alloy which can achieve the strength of the high strength ZK60 wrought magnesium alloy.
