Abstract: PURPOSE: An alloy is provided which has superior ordinary temperature strength and elongation by adding Ca to a Mg-Zn alloy. CONSTITUTION: The high strength Mg-Zn-Ca alloy comprises 5.0 to 6.5 wt.% of Zn, 0.1 to 0.5 wt.% of Ca and a balance of Mg. The tensile strength and elongation of the Mg-Zn-Ca alloy are much more increased compared to a Mg-6 wt.% Zn binary alloy due to grain micronization by addition of Ca according to the increase of an amount of Ca. On the contrary, the strength and elongation of the Mg-Zn-Ca alloy are decreased since a compound formed induces brittle fracture when the amount of Ca becomes 0.5 wt.% or more. Furthermore, the Mg-Zn-Ca alloy represents the similar to or more ordinary temperature tensile properties than an existing typical a Mg-Zn alloy of ZK61 and ZC63 alloys. The Mg-Zn-Ca 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 Mg alloy structural material since the Mg-Zn-Ca alloy has the almost similar strength to an existing Mg-Zn-Zr alloy which represents the highest strength among the currently known Mg alloys and the Mg-Zn-Ca alloy is profitable in the aspects of production cost.

Abstract translation: 目的：提供通过向Mg-Zn合金中添加Ca而具有优异的常温强度和伸长率的合金。 构成：高强度Mg-Zn-Ca合金含有5.0〜6.5重量％的Zn，0.1〜0.5重量％的Ca和余量的Mg。 与Mg-6重量％的Zn二元合金相比，Mg-Zn-Ca合金的拉伸强度和伸长率通过根据Ca量的增加由于添加Ca而导致的颗粒微粉化而大大增加。 相反，Mg-Zn-Ca合金的强度和伸长率降低，因为当Ca含量为0.5重量％以上时，形成的化合物诱发脆性断裂。 此外，Mg-Zn-Ca合金表现出与现有典型的ZK61和ZC63合金的Mg-Zn合金相似或更高的常温拉伸性能。 Mg-Zn-Ca合金由于其重量轻而适用于汽车，飞机等的结构材料，并且可用作现有Mg合金结构材料的替代材料，因为Mg-Zn-Ca合金具有 与目前已知的Mg合金和Mg-Zn-Ca合金中代表最高强度的现有Mg-Zn-Zr合金几乎相似的强度在生产成本方面是有利可图的。
