This work focuses on the mechanical behavior of austenitic stainless steels with a bimodal grain size distribution. A first part, self-sufficient, is dedicated to the improvement of the elaboration process and a second part, more consequent, proposed

The refinement of grains in a polycrystalline material leads to an increase in strength but as a counterpart to a decrease in elongation to fracture. Different routes are proposed in the literature to try to overpass this strength-ductility dilemma,
