AbstractThis research project aims at studying the relationship between the microstructure and the fracture properties of a 316L stainless steel fabricated using two different additive manufacturing processes (LPBF and WAAM). Different microstructures obtained after different thermomechanical treatments will be tested by means of impact and fracture toughness tests. Micromechanical modeling will be used to determine the effect of the microstructure on the fracture properties. The correlation between results from both tests will also be established.
ProfileEngineer and / or Master of Science - Good level of general and scientific culture. Good level of knowledge of French (B2 level in french is required) and English. (B2 level in english is required) Good analytical, synthesis, innovation and communication skills. Qualities of adaptability and creativity. Teaching skills. Motivation for research activity. Coherent professional project.

Prerequisite (specific skills for this thesis):
Metallurgy, Microstructural characterization methods, fracture mehanics, mechanical testing.
