Beschreibung
Zusammenfassung:	The invention relates to a ferrous alloy powder for additive manufacturing comprising an homogeneous distribution of endogenous nitrides and/or carbonitrides of at least one element chosen among a group consisting of titanium, aluminium, chromium, boron, hafnium, vanadium, zirconium, silicon, niobium, tantalum and REM, the nitrogen content of such ferrous alloy powder being above the solubility limit of nitrogen in such meta, and to the manufacturing process of such powder. L'invention concerne une poudre d'alliage ferreux pour la fabrication additive comprenant une distribution homogène de nitrures et/ou carbonitrures endogènes d'au moins un élément choisi parmi un groupe constitué par le titane, l'aluminium, le chrome, le bore, l'hafnium, le vanadium, le zirconium, le silicium, le niobium, le tantale et le REM, la teneur en azote d'une telle poudre d'alliage ferreux étant supérieure à la limite de solubilité de l'azote dans de tels méta, et le procédé de fabrication d'une telle poudre.
