  • METHOD FOR FABRICATING A NITROGENOUS STEEL MATERIAL
    Publication number: 20240139812
    Abstract: The present disclosure generally relates to a method for fabricating a nitrogenous steel material (200). The method comprises preparing a material powder in a powder reservoir (120) of an additive manufacturing apparatus (100). The material powder comprises: a metal powder comprising iron; and an alloying powder comprising nitrogen. The method further comprises performing an additive manufacturing process under atmospheric pressure, the additive manufacturing process comprising: displacing layers of the material powder from the powder reservoir (120) to a build platform (130) of the additive manufacturing apparatus (100); and fusing the layers of material powder on the build platform (130) to fabricate the nitrogenous steel material (200).
