| Abstract: | Heat-resistant magnesium alloys and their development are reviewed. Mg-Al, Mg-Zn, Mg-RE, Mg-Th, Mg-Ag system alloys, rapid solidification magnesium alloy and magnesium-based composite in heat resistance are introduced. It suggested that Mg-RE system alloys can be rapidly developed because of their excellent heat-resistant property, but the alkaline earth metal elements can partially substitut the expensive RE elements. The heat-resistant phases and structures are very important to those alloys for their high strength and heat-resistant stability at elevated temperatures. |
