摘要：
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.
