Abstract: PURPOSE: An alloy for casting is provided which has superior corrosion resistance, ordinary temperature strength and elongation by adding Mn as a third element to a Mg-Zn binary alloy. CONSTITUTION: The high strength corrosion resisting Mg alloy for casting comprises 3.0 to 6.5 wt.% of Zn, 0.7 to 1.3 wt.% of Mn and a balance of Mg. The Mg-Zn-Mn alloy has superior corrosion resistance and tensile properties compared to an existing typical magnesium alloy AZ91C alloy. The Mg-Zn-Mn alloy is suitable for a structural material of an automobile, airplane, etc. due to its light weight and can be used as a substitutional material for an existing AZ based Mg alloy which is most widely used currently since it represents superior corrosion resistance and tensile properties compared to the existing Mg alloy.
Abstract translation: 目的：提供一种用于铸造的合金，其通过将Mg作为第三元素添加到Mg-Zn二元合金中而具有优异的耐腐蚀性，常温强度和伸长率。 构成：用于铸造的高强度耐腐蚀Mg合金包含3.0〜6.5重量％的Zn，0.7〜1.3重量％的Mn和余量的Mg。 与现有的典型镁合金AZ91C合金相比，Mg-Zn-Mn合金具有优异的耐腐蚀性和拉伸性能。 Mg-Zn-Mn合金由于其重量轻而适用于汽车，飞机等的结构材料，可用作现有AZ基镁合金的替代材料，因为它代表了现有的AZ 与现有的Mg合金相比，具有优异的耐腐蚀性和拉伸性能。
