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

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 degrees 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.

Automated summary

The ductility of pure magnesium was enhanced about 3 times at room temperature compared with the initial material due to the proposed concept of shear strain-induced twin orientation regulation (SITOR), where shear deformation was introduced to regulate the initial tension twin orientation, resulting in a larger Schmid factor of basal slip, thus improving the plasticity of pure Mg significantly.
