A value far beyond the forming limit of pure AZ31 when being equivalently deformed. It is observed, that the microstructure evolution in Mg-AZ31 is strongly influenced by twinning. At low strains the [formula presented] twin systems lead to fragmentation of the initial grains. Inside the primary twins, grain refinement takes place by dynamic recrystallization, dynamic recovery and twinning. These mechanisms lead to a final grain size of ≈ 1 μm, while a strong centered ring fibre texture is evolved.enghttps://creativecommons.org/licenses/by-nc-sa/3.0/620CompositeMagnesiumRotary swagingSPDTwinningUltra fine grainedWireArticle
