Abstract: A method of processing a powdered feedstock to form a fabricated component is provided. The fabricated component includes a plurality of grains having a nominal grain size. The method includes providing the powdered feedstock material having a population of phase particulates with a first nominal size distribution disposed within a host matrix material. The method includes building a consolidated component from the powdered feedstock material in an additive manufacturing process, and fabricating the fabricated component from the consolidated component. The first nominal size distribution of the population of phase particulates is sized such that at least a portion of the population of phase particulates persists throughout the additive manufacturing process and is present as a processed population of phase particulates in the consolidated component. In addition, the processed population of phase particulates has a second nominal size distribution effective to produce the nominal grain size of the fabricated component.

Abstract: A method that includes additively manufacturing with an additive manufacturing (AM) system a sub-component that has a locator element. Using a control system of the AM system for positioning a first location of the locator element. Selectively placing a portion of another sub-component adjacent to the locator element, based on the positioning. Then attaching the second sub-component to the first sub-component in a region, wherein the region is based on the positioning knowledge from the control system so as to make a component. A component that comprises a first sub-component that has an AM locator element; and a second sub-component attached to the first sub-component, wherein the locator element is attached to the second sub-component within the same additive manufacturing build chamber as the first sub-component.

Abstract: An apparatus and method for rapid screening of material properties in a plurality of additively manufactured test specimens. The apparatus includes a build plate having the plurality of additively manufactured test specimens disposed on a first substantially planar surface. The plurality of additively manufactured test specimens are coupled to at least one actuator to one of individually or simultaneously translationally displace each of the test specimens along an axis “z”, and perpendicular to the build plane of the build plate to test material properties of each of the plurality of additively manufactured test specimens. A sensor is coupled to each of the plurality of additively manufactured test specimens. Load vs. displacement data may be used to monitor the progression of monotonic and/or cyclic tests of the plurality of additively manufactured test specimens.
