Abstract:
Powder metallurgy has been established in the past sixty years as an old technique, deriving its roots from ancient civilizations, to produce ferrous, copper and zinc products. It was only twenty years ago that it was demonstrated in our laboratory for the first time that it is possible to produce aluminum powder metallurgy parts by using a small addition of magnesium in pure aluminum. It has now become an industry of its own, producing millions of parts used in automotive applications. In this presentation, attempts to extend the powder metallurgy to magnesium metal and its alloys will be discussed. In the last decade, the machine design and its artificial intelligence led to the utilization of 3D metal printing or additive manufacturing. The emphasis has been shifted to the computer aspects of the process although there are still fundamental difficulties on sintering metals.
