| contents | Plastic work partitioning was investigated in extruded AZ31B magnesium alloy under loading orientations promoting slip- or twinning-dominated deformation. Slip-dominated deformation exhibits stable plastic flow with approximately 50$\%$ of plastic work dissipated as heat. In contrast, twinning-dominated deformation initially stores most plastic work, delaying dissipation and promoting rapid strain hardening and early strain localization. The distinct mechanical responses correlate with microstructural evolution, revealing deformation-mechanism-dependent energy storage behavior in HCP magnesium alloys. |
