Influence of texture on dynamic recrystallization and deformation mechanisms in rolled or ECAPed AZ31 magnesium alloy

Equal channel angular pressing (ECAP) and hot rolling are widely used processing routes in magnesium alloys. These routes induce different textures that affect their mechanical properties. In the presentwork, the influence of the texture on dynamic recrystallization (DRX) and deformation mechanisms...

description Equal channel angular pressing (ECAP) and hot rolling are widely used processing routes in magnesium alloys.
