AbstractLocal chemical heterogeneities arising during the casting process can induce microstructural heterogeneities in the final wrought and heat treated part. Under particular circumstances, these microstructural heterogeneities can lead to low fracture energies during Charpy testing. This thesis aims at determining (1) the effect of heat treatments and chemical heterogeneities on the local microstructure and (2) the effect of microstructural heterogeneities on the fracture properties.
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.
