|Abstract||Microstructure and texture evolution of an Mg-7Gd-5Y-1Nd-0.5Zr (EW75) extruded alloy after normal rolling (NR) or cross-rolling (CR) up to three passes with 20% reduction per pass were investigated. The results showed that microstructures with finer grains and weaker textures were developed due to the strain state change during cross-rolling between passes in comparison with the conventional normal rolling. It is suggested that, fewer twins and more secondary particles benefit the dynamic recrystallisation and weaken the texture. Tensile tests conducted at room temperature showed that the material subjected to cross-rolling (CR) after three passes resulted in an enhanced ductility and almost isotropic strength, which mainly attributed to the finer grain structure and texture modification with the (0002) poles distributing more homogeneously.|
