The purpose of this thesis is the understanding and prediction of the behavior of polycrystals composed of two phases. The specificity of this problem is related to the microstructure of the material. This is both made up of several crystallographic phases (allotropic) distinct (the material is in this sense a composite material) and crystals with a variety of shapes and orientations, which is conventional in the case of a polycrystalline material. With the idea that this double source of heterogeneity should affect the behavior at the macroscopic scale but also to smaller scales, we have addressed the problems encountered in forming the case of an austenitic-ferritic steel.L'objet de cette thèse est la compréhension et la prévision du co...
