摘要
综述了高强高韧镁合金及耐热镁合金的现状及发展趋势。从在原有牌号的基础上加入微量合金改进其性能的模式,逐渐转向开发新型合金,大量使用Gd、Y、Nd等稀土元素进行合金强化的模式。针对稀土合金化中存在的问题进行了探讨,对镁合金的发展进行了展望。
The status quo and development trend of high strength and toughness of magnesium alloy and heat-resistant magnesium alloy are summaized. On the basis of original brands adding trace alloy elements to improve its performance model of gradually turn into the development of new alloys, and abundant use of Gd, Y, Nd, and other RE elements to strengthen alloy model. The existing problems for RE alloying are discussed and the development of magnesium alloys is predicted.
