异质结构金属材料的研究进展
Research progress in heterostructure metal materials
摘要
Abstract
The inverted relationship between the strength and plasticity of traditional metal materials limited its application scope.As a new type of composite material,heterostructure metal materials exhibited comprehensive mechanical properties(such as high yield strength,high ductility,and fracture toughness)that traditional homogeneous materials cannot achieve.In this paper,the definition and the types of current mainstream of heterostructure metal materials were introduced.The strengthening and toughening mechanisms of the interaction between soft and hard regions were summarized in heterostructure metal materials at the micro level such as heterostructure deformation-induced strengthening,strain distribution,delayed necking,interface influence zone,etc.Finally,the potential development aspects of heterostructure metal materials in the future are prospected.关键词
