Texture and Mechanical Properties of Extruded AA6063 Aluminum Alloy

Abstract

The extrusion process imposes a large amount of deformation on the material, resulting in complex changes in microstructure morphology and crystallographic texture, making the predictions of the final mechanical properties very challenging. In this research, the texture and the mechanical properties of AA6063 aluminum extruded profiles are investigated. This alloy adopts a recrystallized microstructure with equiaxed grains and a typical texture. The plastic anisotropy is compared with a calculation method considering only the texture effect. Some attempts were made to numerically reproduce specific experimental results by accounting for certain restauration mechanisms.
