Abstract: Embodiments of a method for producing powder mixtures having uniform dispersion of ceramic particles within larger superalloy particles are provided, as are embodiments of superalloy powder mixtures. In one embodiment, the method includes producing an initial powder mixture comprising ceramic particles mixed with superalloy mother particles having an average diameter larger than the average diameter of the ceramic particles. The initial powder mixture is formed into a consumable solid body. At least a portion of the consumable solid body is gradually melted, while the consumable solid body is rotated at a rate of speed sufficient to cast-off a uniformly dispersed powder mixture in which the ceramic particles are embedded within the superalloy mother particles.

Abstract: A method for manufacturing a metallic article includes providing or obtaining a metallic material in powder form, using an additive manufacturing process, building the metallic article from the powder-form metallic material, layer-by-layer, in a build direction, wherein as a result of the additive manufacturing process, the metallic article comprises columnar grain structures oriented in the build direction, and conveying the metallic article through a gradient furnace in a direction of conveyance from a first area of the gradient furnace to a second area of the gradient furnace to increase a size of the columnar grain structures in the metallic article. The metallic article is conveyed through the gradient furnace in an orientation such that the columnar structures oriented in the build direction are substantially parallel to the direction of conveyance.

Abstract: A method for hot isostatic pressing includes the steps of providing or obtaining an article of manufacture, which optionally includes a copper or nickel alloy, disposing the article of manufacture in a shroud, the shroud defining an enclosed volume wherein the article of manufacture is disposed, the shroud being configured as a multi-piece joined structure to retard gaseous mass transport from outside the shroud to inside the enclosed volume, disposing the shroud in a containment vessel of a hot isostatic pressing apparatus and disposing a getter material in the shroud and/or in the containment vessel, and introducing an inert gas at an elevated temperature and pressure into the containment vessel for hot isostatic pressing.
