Hot working behavior of 2205 austenite-ferrite duplex stainless steel characterized by constitutive equations and processing maps

▶ The flow stress is well fitted by the hyperbolic sine equation. ▶ The activation energy for hot deformation is about 479 kJ mol−1. ▶ Processing map indicates no instability in low and medium strain rates. ▶ Dynamic restoration processes hinder flow instability at low and medium strain rates.
