High-temperature plasticity of two-phase alloys: Constitutive laws and microstructure evolution

Modelling high-temperature deformation of two-phase alloys present some specific difficulties compared to the similar problem in pure metals. Some of the open questions associated with these specificities are reviewed. Special attention is given to the relative importance of internal stress and structural hardening, to the derivation and parameter identification of constitutive laws in industrial alloys, and to microstructure evolution during plasticity.
