A newly developed rotation-shear model on the atomic motion during {10 (1) over bar2} twinning in magnesium and its alloys is proposed. In this model, the movement of the twinned atoms is considered as the combination of a rotation by 16 degrees and a subsequent shear along the twinning direction [(1) over bar 011]. Besides, the absolute motion vectors of atoms located in certain atom layers are calculated and summarized into general formulae, by which the movement of any specific atom during twinning can be predicted accurately.
