摘要:

近年來，隨著能源問題和環(huán)境問題的日益嚴峻，作為輕量化合金代表之一的鎂合金得到了人們普遍的關(guān)注。特別是低合金化鎂合金，因其具有優(yōu)異的可加工性能、好的耐蝕性、低成本（密度）以及可提高鎂合金塑性等優(yōu)勢而引起了國內(nèi)外學者的廣泛關(guān)注。然而，低合金含量鎂合金獲得的絕對強度難以滿足實際的工況需求，使其應用面臨著嚴峻的挑戰(zhàn)，高強度低合金化鎂合金可進一步拓展鎂合金的應用范圍。綜述了近年來高強度低合金化鎂合金的研究進展，系統(tǒng)分析了不同體系高強度低合金化鎂合金的高強高韌化機理，并展望了未來高性能低合金化鎂合金研究的發(fā)展方向。

Abstract:

In recent years, with the energy and environmental problems being gradually serious, the research on Mg alloy, which is one of the representatives of lightweight alloys, has received greatest attention. In particular, low-alloyed Mg alloy has attracted wide attention from scholars at home and abroad due to their excellent processing properties, high corrosion resistance, low cost (density) and improved ductility. However, it is always a great challenge to achieve high absolute-strength for this low-alloyed Mg alloy to satisfy the requirement for the practical applications, high-strength and low-alloyed magnesium alloy can further broaden the application scope of Mg alloy. In this regard, the research progress of high-strength and low-alloyed Mg alloy in recent years is reviewed in this paper. The strengthening and toughening mechanism of high-strength and low-alloyed Mg alloys in different alloying systems are comprehensively analyzed, and the development direction of high-performance and low-alloyed Mg alloy is prospected.
