Microstructure, texture and mechanical properties of extruded Mg-xGd sheets (x = 1.0, 1.5, 2.0 and 2.5 wt%) were discussed, and microstructural evolution of an Mg-1.0Gd alloy during extrusion were investigated. The extruded Mg-xGd sheets presented a fully recrystallized microstructure. The texture with [112 over line 1]-[202 over line 1] double fibre orientations was observed in all the extruded sheets, and texture weakening was observed with increasing Gd content. With an increase in Gd content, the tensile strength of the sheets gradually increased mainly due to the fine grain size and more ...
