Résumé des résultats (Abstract) (Allemand)

The project aims at reducing the scrap rate of semi-finished products made of a new red gold alloy, by (1) determining the critical process values, and (2) explaining the physical reasons at the origin of the problems by microstructural investigations at different scales. The scientific part of the project will focus on the coupling effects between the phase transformation, internal stresses and recrystallization phenomena.
