Abstract
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.

Dedicated to Dr. František Kroupa in honour of his 70th birthday.
It is a pleasure for the authors to dedicate this paper to Dr. Kroupa. As one of the main contributors to the development of physical metallurgy and dislocation theory, he is among the ones who made possible the understanding of the behaviour of everyday's life materials and their continuous improvements. As a visitor in Grenoble, in Hamilton as well as a guest in Prague, he has helped all of us more than we could say by his encyclopaedic knowledge of materials science and his constant and friendly ability to discuss new results and new ideas.
