  • Patent number: 11865617
    Abstract: Methods and apparatuses for identifying an additive manufacturing process for unused output material of an atomization process are described. The method comprises determining a set of characteristics of output material that is unused in a first additive manufacturing process. The method further comprises determining a respective set of parameters associated with respective input material of each of a set of other additive manufacturing processes. The method of further comprises identifying one of the set of other additive manufacturing processes that accepts the output material as input material based on the characteristics of the output material and based on respective sets of parameters.

  • Patent number: 11692254
    Abstract: Novel High-Entropy Alloy (HEA) compositions are particularly suited to welding applications. The mixtures contain at least the elements nickel, manganese, cobalt, chromium, vanadium, molybdenum, and iron. The % weight of the constituents varies in accordance with the detailed description contained herein, with tolerances in the range of ±4% for major alloying elements and ±1% for minor alloying elements. The mixture may also contain a small amount of Aluminum, Titanium, and Boron with a tolerance in the range of +/?1% or, more preferably, +/?0.5% In accordance with the invention, the compositions above may be integrated into HEA welding products using cored wire and welding electrode manufacturing techniques, preferably starting with vacuum melted rolled alloys. One manufacturing process uses the compositions as an alloyed strip formed around the appropriate ground/crushed alloys to make commercially viable fabricated welding products.

  • Publication number: 20220088608
    Abstract: Methods and apparatuses for producing spherical metallic powders through continuous ball milling are described. The apparatus comprises a comminution component including an inlet to receive a metallic material at a first region within the comminution component and an outlet to dispense the metallic powder from a second region within the comminution component. The apparatus further comprises a plurality of grinding components to grind the metallic material, the plurality of grinding components being arranged within the comminution component. The apparatus comprises a drive component, connected with the comminution component, to induce movement of the metallic material and the plurality of grinding components within the comminution component such that the metallic material is fragmented through contact with the plurality of grinding components at the first region and an external surface of the fragmented metallic material is altered at the second region to produce the metallic powder.
