Influence of alloying elements on mechanical properties of Al-Li plates①
（Beijing Institute of Aeronautical Materials, Beijing 100095, China）
Abstract:The effect of alloying elements such as Cu, Mn and Zr on the mechanical properties of the Al-Li plates was studied, and the grain structure, crystallographic texture and precipitates were also investigated. It is found that the element Zr has a two-fold effect on the anisotropy of mechanical properties; the addition of element Mn can reduce the crystalline texture and the anisotropy of Al-Li plates. However, the effect of Cu element appears less pronounced.
Key words: aluminum-lithium alloy; anisotropy; texture; microstructure
