Abstract: In the current paper, pre-compression is performed along the rolling direction (RD). Subsequently, the samples are deformed in plane-strain compression along the transverse direction (TD) and not allowed to expand in the normal direction (ND). The effect of plane-strain compression on the texture and anisotropy modification of a pre-twinned hot-rolled Mg–3Al–1Zn alloy is investigated by EBSD observation. The results reveal that the generation of double twins in the previous twins dominates the plane-strain pre-compression along TD while the twinning is difficult to occur in the matrix due to the constraint along ND. Additionally, the double twins generated in the previously formed twins effectively modify the compression behavior and enhance the compressive yield strength of the pre-compressed samples along ND. The anisotropy along RD, TD and ND is decreased. [Copyright &y& Elsevier]
