Abstract: A process for additively controlled surface features of a gas turbine engine casing. The process comprises forming the casing having an inner surface and an outer surface opposite the inner surface; forming a surface feature on the casing proximate the inner surface, wherein the surface feature comprises a structure on the inner surface configured to align or misalign with respect to a flow direction of a working fluid in a flow path of the casing.

Abstract: A rotary component may comprise a first structure configured to rotate about an axis and a second structure configured to rotate about the axis. A support structure may be coupled to the first structure at a first attachment location and to the second structure at a second attachment location. The support structure may be configured to separate from the first structure and the second structure in response to a centrifugal force generated by the first structure and the second structure rotating about the axis.

Abstract: A process for additive manufacturing of a metal alloy material is provided that includes: a) providing a feedstock powder comprising base powder particles with nanoparticles attached to surfaces of the base powder particles; b) providing an additive manufacturing system with a laser power source relatively movable at a scan speed; c) wherein the additive manufacturing system has a process window for the feedstock powder; and d) exposing the feedstock powder to a predetermined power input from the laser power source at a predetermined scan speed to produce the metal alloy material. The concentration by volume of nanoparticles within the feedstock powder is such that independent first and second microstructures may be produced within the metal alloy material.
