摘 要:综述了耐热镁合金及其研究进展。介绍了Mg-Al、 Mg-Zn、 Mg-RE、 Mg-Th、 Mg-Ag合金系及镁基复合材料、 快速凝固镁合金在耐热性能方面的发展;认为Mg-RE系合金由于其优良的耐热性能,可在我国大力发展, 但碱土金属可部分代替昂贵的稀土元素。 对这些合金来说, 研究耐热相及结构对提高合金的高温强度和热稳定性是非常重要的。
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.
