Hot working analysis of a CuZn40Pb2 brass on the monophasic (β) and intercritical (α+β) regions

The modeling of the flow curves was carried out by physically-based constitutive equations considering the coexistence of recovery, work hardening and recrystallization on a two-phase material. The β phase, rich in Zn, enhanced the dynamic recovery and retarded the recrystallization kinetics, while the opposite was determined for the α phase, rich in Cu.
