Partitioned GAM maps with threshold values of 0.35° and 0.8° for the microstructures in: (a) as-forged state, deformed state (b) with ε_t of −0.22 at $\dot{\epsilon }$ of 10 s⁻¹, (c) with ε_t of −0.40 at $\dot{\epsilon }$ of 10 s⁻¹, (d) with ε_t of −1.11 at $\dot{\epsilon }$ of 10 s⁻¹, and (e) with ε_t of −0.40 at $\dot{\epsilon }$ of 10⁻³ s⁻¹.
