Abstract
A hybrid extension twin structure generated by a cross compression of the hot-rolled Mg alloy along the transverse direction (TD) and the rolling direction (RD) is employed to reassign the crystallographic orientation along RD, TD and normal direction (ND). The orientation redistribution leads to multi-deformation modes during both the compression and the tension deformation. The grain refinement by twin lamellas and the crystallographic orientation redistribution greatly reduces the tension–compression yield asymmetries along RD, TD and ND in the pre-strained sample. The corresponding mechanism are studied and discussed, too.
