Abstract (en)

[origin: WO2020249808A1] Disclosed is a method for manufacturing a metal part made from titanium, by sintering a powder, the method comprising a step of mixing a spherical titanium powder and a dendritic titanium powder in order to form a mixture, a step of agglomerating the mixture of titanium powders by compaction with a ram moving at a speed of more than 2 m·s-1, the mixture of titanium powders being free of binders, in particular organic binders, forming a green body or agglomerate suitable for sintering having a density above 78%, and preferably 80%, of the density of the solid metal, and a step of sintering.
