    Abstract: An embodiment of a method includes fabricating a first single crystal boule having a uniform composition and grain orientation. The first uniform single crystal boule is divided into a first plurality of layered shapes. The shapes of the first plurality are stacked with at least a second plurality of layered shapes along a first axis. The second plurality of layered shapes have at least one physical aspect differing from at least one corresponding physical aspect of the first plurality of layered shapes. The first plurality of layered shapes and at least the second plurality of layered shapes are joined via a field assisted sintering technique (FAST) to form a bulk component.

    Abstract: Aspects of the disclosure are directed to treating a substrate, the substrate including at least one of a refractory metal or a ceramic material, and depositing a media onto the treated substrate to generate a casting core. Embodiments include a fixture, a substrate located on the fixture, the substrate including at least one of a refractory metal or a ceramic material, and a delivery head that deposits media onto the substrate to generate a casting core. Aspects are directed to a core configured for casting a component, the core comprising: a substrate that includes at least one of a refractory metal or a ceramic material, and media deposited on the substrate, the media having a dimension within a range of between 0.5 and 500 micrometers.

    Abstract: Disclosed is a method for controlling a microstructure of an inorganic material includes providing a structure that has a first region of an inorganic material having a first microstructure and a second region that is thermally responsive to electromagnetic radiation, the second region being adjacent the first region, and indirectly heating the first region by thermally activating the second region, using electromagnetic radiation, to generate heat. The generated heat converts the first microstructure of the inorganic material to a second, different microstructure. The method can be applied to control a microstructure of an inorganic coating on an inorganic fiber.

    Abstract: A method of making a ceramic composite component includes providing a fibrous preform or a plurality of fibers, providing a first plurality of particles, coating the first plurality of particles with a coating to produce a first plurality of coated particles, delivering the first plurality of coated particles to the fibrous preform or to an outer surface of the plurality of fibers, and converting the first plurality of coated particles into refractory compounds. The first plurality of particles or the coating comprises a refractory metal.

    Abstract: Components with improved erosion resistance are disclosed. A surface of the component or a substrate of the component is modified by coating the substrate with an elastomer layer. The elastomer layer is then modified by embedding hard particles onto an outer side of the elastomer layer. The hard particles exhibit higher fractured toughness providing enhanced erosion protection. The elastic properties of the elastomer experience little reduction because the surface embedded particles are located only at the outer side or outer surface of the elastomer layer. Therefore, the bond between the inner side of the elastomer layer and the substrate or component surface is not interfered with and the potential for electro-chemical corrosion and poor adhesion are not increased by the presence of the hard particles as the hard particles are located away from the inner face between the elastomer layer and the substrate.
