Abstract: A method of forming a metal component with two and three dimensional internal functionally graded alloy composition gradients includes forming the component by a powder based layer-by-layer additive manufacturing process. The areal composition distribution of each powder layer is determined by simultaneously depositing different powders and powder mixtures through a mixing valve attached to a single nozzle during powder deposition. The layers are then sintered with a directed energy source to form a forging preform. The preform is then forged to form a component.

Abstract: A method of making a part including a solid portion with an internal passage includes building the part using an additive manufacturing process that builds the part on a layer-by-layer basis. The solid portion of the part is formed. Forming the solid portion includes fusing the solid portion. A solid core is formed within at least a portion of the internal passage. Forming the solid core includes fusing the solid core and forming an attachment feature on the solid core. Material that is not fused, either semi-sintered or un-sintered, is positioned between the solid portion and the solid core. At least a tensile, compressive, vibratory, or torsional force is applied to the solid core at the attachment feature. The solid core is then removed from the part.
