Abstract
The microstructures of the as-rolled magnesium alloy subjected to dynamic plastic deformation along the rolling direction have been investigated. Mostly one {101¯2} twin variant or a twin variant pair is activated in a grain, leading to a parallel {101¯2} twin lamellar structure. At the stage of twinning-dominated deformation (ε < â¼8%), lamellar thickness decreases significantly with strain, from 5.55 to 2.49 μm. The evolution of lamellar thickness during deformation is directly related to {101¯2} twin activity. When plastic strain is greater than â¼8%, the twin lamellar structure disappears because the volume fraction of twins almost saturates at a value of â¼90%.
