Abstract

Local texture in hot extruded MgAl9Zn1 alloy has been studied using individual grain orientation measurement (BKD, “Automated EBSD”) in the SEM. In the shaft of a partial extrudate through a circular die orifice, a <0001> ring fiber texture has formed which continuously changes into a spiral fiber texture in the bottom neck. The flow tube of the internal back-end extrusion defect has a distinctly different texture whereby the (0002) lattice planes are preferentially aligned parallel to the radial and the extrusion directions. The formation of this texture is explained by basal glide, the pile-up of the hard billet mantle, and the inhomo-geneous metal flow during the extrusion process.
