Powder metallurgy applied to multimaterials. Marly laboratories and technical centres have begun to work Oil the possibility of creating multimaterial composites rising Powder Metallurgy. This process call be used to avoid assembly problems and to obtain dimensionally accurate products. Dynamic compaction ('High-Speed Compaction') and conventional compaction are two possible methods. which call he compared using a laboratory press equipped with test instrumentation. For certain powders, High-Speed Compaction can improve the properties in the green state and apply favourable changes to the sintering conditions. Compaction is followed by conventional sintering. Various types of powder (metal powders, hard powders and ceramic powders) are used in this project, giving rise to many possible applications. This presentation shows the initial results obtained by the research group.
