급속응고 Mg-Zn-Y 합금의 성형특성

Materials Properties of Rapidly Solidified Mg-Zn-Y Alloys

Light Mg alloy stands on the center of investigation due to the high potential of industrial application not only to the structural, but also to the functional fields. However, the intrinsic low strength and corrosion resistance have limited to extend its industrial use. In order to overcome the disadvantage, various attempts have been come to the modification of composition, resulting in finding Mg-Zn-Y alloys. The cast Mg-Zn-Y alloy leads to the high strength and hardness, low friction coefficient and low interfacial energy in both the ambient and elevated temperature.
