  • In situ alloying of Cu—Cr—Nb alloys using selective laser melting
    Patent number: 11859272
    Abstract: In situ alloying of elemental Cu, Cr, and Nb powder using laser melting to form a Cu—Cr2Nb alloy. The elemental powders are initially mixed to form a homogeneous mixture, which mixture is then subjected to laser radiation to melt the mixture. In the melt, the Cr and Nb react to form Cr2Nb, which when cooled form precipitates that are dispersed in a nearly pure Cu matrix to thus dispersion strengthen the material. The methods can be used to additively manufacture a 3D component of Cu—Cr2Nb alloy using a selective laser melting machine.
