9 10 The mechanical response of magnesium AZ31 processed 11 using severe plastic deformation is characterized using a 12 two-surface, pressure-insensitive plasticity model. The 13 model captures the 3D plastic anisotropy and the tension-14 compression asymmetry as the behavior evolves during 15 straining. The model may be viewed as a reduced-order 16 quasi-crystal plasticity model, whereby the two activation 17 surfaces represent glide-and twinning-dominated flow.
