Features of structure-sensitive hard magnetic alloy Fe – 25 wt. % Cr – 15 wt. % Co manufactured by Laser Powder Bed Fusion

Abstract It was studied the structure of alloy manufactured on the RussianSLM FACTORY unit by laser powder bed fusion. The powder was produced by gas atomization from ingots on a HERMIGA 75/3VI unit. By constructing a hesteresis loop, data were obtained that indicate an increase in the magnetic characteristics (Br, Bd, Hcb, Hcm and BHmax) in additive samples in comparison with similar ones obtained by foundry technologies.
