Abstract
A method of fabricating parts out of metallic, intermetallic, ceramic, ceramic matrix composite, or metal matrix composite material with discontinuous reinforcement, includes melting or sintering powder particles by means of a high-energy beam. The powder used is a single powder of particles that present sphericity lying in the range 0.8 to 1.0 and of form factor lying in the range 1 to √2, each powder particle presenting substantially identical mean composition, and the grain size distribution of the particles of the powder is narrowed around the mean diameter value d50% in such a manner that: (d90%−d50%)/d50%≤0.66; and (d50%−d10%)/d50%≤0.33; with a 'span': (d90%−d10%)/d50%≤1.00.
