Method for manufacturing a component containing an iron alloy material

Abstract

In a method for manufacturing a component containing an iron alloy material, a pulverulent pre-alloy is provided. The pre-alloy comprises, in wt. %, 0.01 to 1% C, 0.0.01 to 30% Mn, ≤6% Al, and 0.05 to 6.0% Si, the remainder being Fe and usual contaminants. The pulverulent pre-alloy is mixed with at least one of elementary Ag powder, elementary Au powder, elementary Pd powder and elementary Pt powder so as to produce a powder mixture containing 0.1 to 20% of at least one of Ag, Au, Pd and Pt. The powder mixture is applied onto a carrier ( 16 ) by means of a powder application device ( 14 ). Electromagnetic or particle radiation is selectively irradiated onto the powder mixture applied onto the carrier ( 16 ) by means of an irradiation device ( 18 ) so as to generate a component from the powder mixture by an additive layer construction method.
