An unusual extrusion texture in Mg-Gd-Y-Zr alloys
An unusual extrusion texture in Mg-Gd-Y-Zr alloys
Texture evolution is studied by EBSD in Mg–9Gd–4Y–0.4Zr (GW94), Mg–5Gd–4Y–0.4Zr (GW54), and Mg–5Gd–0.4Zr (GW50) alloys after processing with two extrusion-ratios of 19:1 and 8:1. While the alloys show common extrusion textures at the low extrusion-ratio of 8:1, an unusual extrusion texture is observed in the GW94 alloy at the high extrusion-ratio of 19:1 with the (0001) basal planes aligned perpendicular to the extrusion axis. This unusual texture decreases at lower extrusion-ratios and/or lower alloy contents. It is proposed that rare-earth (RE) elements modify the texture by retarding recrystallization in solute drag effects on grain boundaries and pinning effects of RE-rich precipitates.

Abstract
Texture evolution is studied by EBSD in Mg–9Gd–4Y–0.4Zr (GW94), Mg–5Gd–4Y–0.4Zr (GW54), and Mg–5Gd–0.4Zr (GW50) alloys after processing with two extrusion-ratios of 19:1 and 8:1. While the alloys show common extrusion textures at the low extrusion-ratio of 8:1, an unusual extrusion texture is observed in the GW94 alloy at the high extrusion-ratio of 19:1 with the (0001) basal planes aligned perpendicular to the extrusion axis. This unusual texture decreases at lower extrusion-ratios and/or lower alloy contents. It is proposed that rare-earth (RE) elements modify the texture by retarding recrystallization in solute drag effects on grain boundaries and pinning effects of RE-rich precipitates.
