Abstract: A method of forming a directionally-solidified casting component using a casting system is provided. The casting system includes a chamber having a heating zone and a cooling zone separated by a baffle plate. The method includes pouring an alloy in a liquid state into a mold shell. The mold shell is positioned on a chill plate within the heating zone. The method further includes moving the mold shell from the heating zone into the cooling zone. The alloy transfers from the liquid state to a solid state within the mold shell while moving the mold shell from the heating zone to the cooling zone. The method further includes contacting the mold shell with a heat transfer member.

Abstract: Embodiments of the disclosure provide a system including: an enclosure having an interior sized to enclose and the workpiece and form a vacuum and pressurized atmosphere within the interior. A plurality of thermal applicators may be in thermal communication with first and second portions of the interior. First and second thermal applicators may independently heat and cool the first and second portions of the interior. The first thermal applicator may apply a first thermal treatment to a first portion of the workpiece in the first portion of the interior. A second thermal applicator may apply a second thermal treatment to a second portion of the workpiece in the second portion of the interior independently of the first thermal treatment.

Abstract: A thermal management article is disclosed including a substrate and a first coating disposed on the substrate. The first coating includes a first coating surface and at least one passageway disposed between the substrate and the first coating surface. The at least one passageway defines at least one fluid pathway. A method for forming a thermal management article is disclosed including attaching at least one passageway to a substrate. The at least one passageway includes a passageway wall having a wall thickness and defines at least one fluid pathway. A first coating is applied to the substrate and the passageway wall, forming a first coating surface. The at least one passageway is disposed between the substrate and the first coating surface.

Abstract: A method of controlling an extent of a thermal barrier coating (TBC) sheet spall and a hot gas path (HGP) component are disclosed. The method provides an HGP component having a body with an exterior surface. Controlling the extent of the TBC sheet spall includes forming a TBC over a selected portion of the exterior surface of the body. The TBC includes a plurality of segments in a cellular pattern. Each segment is defined by one or more slots in the TBC, and each segment has a predefined area such that the extent of the TBC sheet spall is limited by the predefined area of each of the plurality of segments that constitute the TBC sheet spall.
