    Abstract: A turbine blade having an airfoil portion includes a first ceramic matrix composite (CMC) component having a first outer surface and a second ceramic matrix composite (CMC) component having a second outer surface. The second CMC component is positioned adjacent the first CMC component such that the first outer surface and the second outer surface align with one another and at least partially define the airfoil portion. A ceramic bead is at least partially formed at an interface between the first CMC component and the second CMC component. The formation of the bead melts a portion of the first CMC component and the second CMC component, such that the ceramic bead, the first CMC component, and the second CMC component become a single contiguous component and the bead fixedly attaches the first CMC component and the second CMC component. The bead includes a bead outer surface that extends outward beyond the first outer surface and the second outer surface and an overlayer is deposited onto the airfoil portion, the overlayer bonded to the first outer surface, the second outer surface, and the bead outer surface.

    Abstract: A method of welding with low shrinkage stress, including forming an excavation (42, 70) in a surface (24, 76) of a substrate (24, 76) with a shallow geometry (D, W, A) limited to surfaces oriented within 45 degrees of the surface. Molten weld metal (46, 80) in the excavation solidifies with largely unopposed shrinkage vectors directed toward the substrate within 45 degrees of normal to the surface. The molten metal may be warmed along the sides of the excavation (42A, 42B) so it solidifies upward (56) from the bottom, rather than from the sides inward. A metal insert (78, 84) may be fitted into the excavation and welded along the interface between them using a process that minimizes mechanical restraint on the weld by accommodating weld shrinkage.

    Abstract: A method, including: detecting in a nondestructive manner a marker (10, 12, 50, 70, 76, 78) that is fully submerged in a substrate (14) to obtain spatial information about the marker; detecting in a nondestructive manner the marker after a period of time to obtain a change in the spatial information; and using the change in the spatial information to determine a change in a dimension (30) of the substrate. The method may be used to measure creep in a gas turbine engine component.

    Abstract: A method for forming a dispersion strengthened alloy. An alloy material (8) is melted with a heat source (28) to form a melt pool (30) in the presence of a flux material (26), and strengthening particles (36) are directed into the melt pool such that the particles are dispersed within the melt pool. Upon solidification, a dispersion strengthened alloy (44) is formed as a layer or weld joint bonded to an underlying substrate or as an object contained in a removal support.
