异构镁制备及强韧化机理的研究现状

Current status of research on preparation and strengthening/toughening mechanism of heterogeneous magnesium

镁合金以及镁基复合材料强度和塑性通常存在矛盾关系,在基体中引入异质结构是解决该矛盾的新方法。近年来,异构镁合金和异构镁基复合材料的制备以及强韧化机理的研究受到广泛关注。本文从异构镁合金以及异构镁基复合材料的常见种类、制备工艺、强韧化机理分析的角度进行了综述,总结了异质结构镁的研究现状并对其进行了展望。

The strength and plasticity of magnesium alloys and magnesium matrix composites are usually in contradiction,and the introduction of heterostructures in the matrix is a new way to solve the contradiction.In recent years,the preparation of heterostructured magnesium alloys and heterostructured magnesium matrix composites as well as the research on the mechanism of strengthening and toughening have received wide attention.This paper reviewed the common types of heterostructured magnesium alloys and heterostructured magnesium matrix composites,the preparation process,and the analysis of the toughening mechanism,and summarized the current status of the research on magnesium heterostructures and made a prospect for it.
