Abstract
High strain-rate rolling (HSRR) was successfully used to produce Mg–6.0 Zn–0.5 Zr sheets at 250–400 °C. All the sheets have ultrafine-grained structures and exhibit excellent strength and ductility. Extensive deformation twinning, production of high-density dislocations in twins, subsequent continuous dynamic recrystallization (DRX) and discontinuous DRX contribute to the feasibility of HSRR and to the ultrafine-grained structures. The excellent mechanical properties are ascribed to the ultrafine grains, low dislocation density and weakened basal texture in the final structure.
