准晶相增强高性能镁合金的研究进展

Research Progress in Quasicrystal-reinforced High Performance Magnesium Alloys

综述了准晶相增强镁合金的制备方法,以及准晶相增强Mg-Zn-Y、Mg-Zn-Al的微观组织和性能特点,介绍了准晶相增强镁合金在国内外的研究及应用进展状况。已有的研究结果表明,镁合金中准晶相的存在对提高合金的室温和高温强度、改善合金塑性有明显作用。

The fabrication methods, mierostrueture and mechanical properties of the quasierystal reinforced magnesium are reviewed. The recent development and application of the high performance magnesium alloys containing quasicrystals are also introduced. The results show that the quasicrystals play great effects to improve the strengthen and elongation of magnesium alloys either at room or high temperatures.
