The role of alloying elements in Al-Mg alloys and their influence on mechanical properties
Al-Mg alloy is an important metal material in the field of lightweight material application.It belongs to the medium and high strength aluminum alloy,with high plasticity,good corrosion resistance and excellent weldability and other advantages,and currently has broad application prospects in aero-space,transportation and military manufacturing.This paper reviews the mechanical properties and ap-plications of aluminum-magnesium alloys,introduces the strengthening mechanism in Al-Mg alloys,fo-cuses on the influence law and mechanism of the main alloying element Mg and its content on micro-structure and mechanical properties in Al-Mg alloys,and discusses in detail the role of Mn,Zr,Ti,Sc,Er,Y and other microalloyed elements on microstructure and mechanical properties of Al-Mg alloys.Fi-nally,based on the current research status of Al-Mg series alloys,the future research directions are pro-posed.
