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