Hot Formability and Texture Formation in Al Alloys
The effect of plastic deformation of Aluminium alloys at elevated temperatures is described and its effects on texture evolution in Aluminium and its alloys. The softening mechanisms involved are recovery, recrystallization and grain boundary sliding which reduce strain hardening and affect plastic deformation also in industrial fabrication and forming processes of Aluminium alloys, like (hot) forming, rolling, extrusion and superplastic forming. These effects that control high temperature formability and the resulting textures and final properties are described.
