| Abstract | In-situ neutron diffraction has been used to measure lattice strains for different grain orientations as a function of applied stress in a solid-solution-strengthened extruded binary Mg-9wt.%Al alloy. An elastic-viscoplastic self-consistent (EVPSC) model of polycrystal plasticity was used to simulate the macroscopic stress-strain curve and the neutron diffraction data, yielding the relative contributions, critical resolved shear stresses and hardening behavior of the available slip and twinning modes. Non-linear behavior was observed during unloading after deforming the material into the fully plastic regime in tension. The model suggests that this non-linear behavior is mainly due to basal slip. |
