Sintered materials - KAMA7M04

Goal(s)

Knowing and mastering the principles of making materials from powders and understanding the genesis of microstructures of sintered materials to find the best compromise costs / properties for pieces whose shape can be complicated. For metals and alloys this route of development represents for economic reasons an industrial activity in very strong growth. For ceramic materials these manufacturing processes are practically unavoidable and the improvement of the properties of ceramics passes through the control of the development of microstructures during sintering.
