Plasticity enhancement in pure magnesium achieved based on initial twin orientation regulation

Abstract

© 2022 Elsevier B.V.In the short communication, the ductility of pure magnesium was enhanced about 3 times at room temperature compared with the initial material based on the proposed concept of shear strain-induced twin orientation regulation (SITOR). The initial tension twin orientation inclines about 30° to the TD-ND plane which is regulated by the introduced shear deformation so that a larger Schmid factor of basal slip is achieved. Due to the promotion of basal slip, the plasticity of pure Mg is improved obviously.
