Effect of composition on recrystallization texture formation of aluminum extrusions

Abstract

This study investigated the influence of the solute concentration and iron on the recrystallization texture formation of an A6063 alloy extruded with the preferred orientation, a commercially available cast A6063 alloy, an alloy containing no Fe, an alloy containing varying amounts of Mg and Si, and the extruded material. The obtained extruded material, the material structure in the extrusion chamber, and the crystal orientation were evaluated using scanning electron microscopy combined with electron backscattering pattern (SEM-EBSP). In the cross-section of the texture of the extruded material, the main orientation was cube; while the main orientation on the surface was crystal grains with a TD
