Objectives

This course provides a rigorous formation for the students in casting and miscellaneous techniques (powder metallurgy, welding, thixoforming, thermal spraying…), physical mechanisms and induced microstructure (1) to model and simulate these processing and (2) to predict the in-life mechanical properties of components.

Targets

This program focuses on liquid, semi-liquid metal processing: casting (sand casting, die casting), powder metallurgy (sintering, metal injection moulding…), welding, high energy processes …. This course will be used in order to optimize the manufacture processing to obtain the right properties for a specific application. Current industrial areas are aeronautics, transportation, nuclear engineering, energy, biomedical engineering, structures…
