Content
The course is based on the analysis of concrete applications to provide the necessary concepts for the understanding, definition and use of technical, functional, economic and / or environmental criteria for the choice of materials and processes Course content : - Materials (and processes) choice : main principles and methodology - Metallic materials for highly stressed mechanical parts, adaptation of mechanical properties by heat treatment processes, influence of parts size - Light structural parts: use of low density metallic materials, engineering polymers or composite materials - Materials for very high temperature parts - Durability of materials (corrosion, polymers aging) - Parts end of life (recycling, ...) Practice The practical work will highlight and observe the effects of corrosion and aging on metals and polymers. The choice of materials will be implemented through case studies through the use of a software for materials choice
