Abstract
The invention is concerned with the production of pieces by powder metallurgy, and, more particularly, the use of powders with spherical particles, such as those obtained by pulverisation, in a gas of a liquid metal or alloy. The metallic powder according to the invention is constituted by granules, each of these comprising an assembly of spherical particles which have been agglomerated by at least 0.5% of gelatin. This powder is prepared by mixing with the spherical particles an aqueous solution of gelatin; a paste is thus obtained which is broken in such a way that granules are obtained by calibration and drying. Application to the production of pieces made of non-oxidising, fire-proof, or other, steels or alloys.
