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 {101-2}-{101-2} double twins in the previous {101-2} twins dominates the plane-strain pre-compression along TD while the {101-2} twinning is difficult to occur in the matrix due to the constraint along ND. Additionally, the {101-2}-{101-2} double twins generated in the previously formed {101-2} 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.
