Estimating the term…
A ferrous alloy powder for additive manufacturing, obtained by atomization with a gas made of at least 95% in volume of nitrogen, the alloy including carbon up to 0.5 wt. %, titanium up to 11.0 wt. %, boron up to 5 wt. %, manganese up to 30 wt. %, aluminium up to 15 wt. %, silicon up to 1.5 wt. %, vanadium up to 0.5 wt. %, copper up to 2 wt. %, niobium up to 2 wt. %, the remainder being iron and residual elements, the powder including endogenous nitrides and/or carbonitrides of at least one element chosen among a group consisting of titanium, aluminium, boron, vanadium, silicon, and niobium, the nitrogen content of such ferrous alloy powder being above the solubility limit of nitrogen in such alloy, at the atomization temperature. A manufacturing method of such powder is also provided.
