摘要：

Using texture analysis and optical microscopy it has been found that, due to the large anisotropy of the hcp lattice, the deformation mechanism predominant during large strain hot rolling of an AZ61 Mg alloy changes from dislocation slip and rotational recrystallization (RRX) to twinning as the sheet thickness is reduced.
