摘要:

    隨著近年來汽車等工業(yè)節(jié)能減排對更高性能輕質(zhì)鎂合金的迫切需求，鎂合金在工業(yè)應(yīng)用中展現(xiàn)出了很大的發(fā)展前途。稀土鎂合金系由于具有高溫強(qiáng)度高、優(yōu)良抗蠕變性能及耐熱性能以及良好的塑性和耐腐蝕性等高性能，已經(jīng)成為越來越受到重視的鎂合金系之一，并在航空航天、電子、汽車、通訊等領(lǐng)域得到了廣泛應(yīng)用。目前，國內(nèi)外已開發(fā)了Mg�睪d、Mg�瞃、Mg�睪d�瞃、Mg�瞃�睪d等一系列稀土鎂合金。綜述了高性能稀土鎂合金的研究進(jìn)展和應(yīng)用現(xiàn)狀，主要介紹了Mg�瞃和Mg�睪d二元和多元合金系的研究開發(fā)及應(yīng)用的新進(jìn)展，以及含長周期堆垛有序結(jié)構(gòu)（Long Period Stacking Ordered Structure，簡稱LPSO結(jié)構(gòu)）的Mg�瞃�瞆n、Mg�睪d�瞆n、Mg�睪d�瞃�瞆n、Mg�瞃�睪d�瞆n合金系的研究現(xiàn)狀。最后，展望了高性能稀土鎂合金的發(fā)展趨勢。

Abstract:

     Along with the urgent need of higher performance light quality magnesium alloys for energy�瞫aving and carbon emission reduction in automobile and other industries of late years, magnesium alloys exhibit much development prospect in industry application. Rare earth magnesium alloy series have been attached more and more importance owing to their high�瞤erformances, including high strength at high temperature, excellent creep resistance & heat resistance, and good plasticity and corrosion resistance, etc. They have been widely used in fields such as aerospace, electronics, automobile, communication, and so on. At present, a series of rare earth magnesium alloys, including Mg Gd, Mg Y, Mg Gd Y, Mg Y Gd, and etc., have been developed worldwide. Current research development and application status of advanced Mg alloys were reviewed, mainly on new development of binary and complex Mg�瞃 and Mg�睪d alloys, as well as on status of Mg Y Zn, Mg Gd Zn, Mg Gd Y Zn and Mg Y Gd Zn alloy series with long period stacking ordered structures. At last, the development trend of advanced Mg alloy was proposed.
