摘要： A method for manufacturing a metallic article includes providing or obtaining a metallic material in powder form, using an additive manufacturing process, building the metallic article from the powder-form metallic material, layer-by-layer, in a build direction, wherein as a result of the additive manufacturing process, the metallic article comprises columnar grain structures oriented in the build direction, and conveying the metallic article through a gradient furnace in a direction of conveyance from a first area of the gradient furnace to a second area of the gradient furnace to increase a size of the columnar grain structures in the metallic article. The metallic article is conveyed through the gradient furnace in an orientation such that the columnar structures oriented in the build direction are substantially parallel to the direction of conveyance.

摘要： A nickel-based superalloy component includes a nickel-based superalloy metal. The nickel-based superalloy metal includes, on a weight basis of the overall superalloy metal: about 9.5% to about 10.5% tungsten, about 9.0% to about 11.0% cobalt, about 8.0% to about 8.8% chromium, about 5.3% to about 5.7% aluminum, about 2.8% to about 3.3% tantalum, about 0.3% to about 1.6% hafnium, about 0.5% to about 0.8% molybdenum, about 0.005% to about 0.04% carbon, and a majority of nickel. In some examples, the component includes a gas turbine engine component, such as a turbine blade or a turbine vane, and the metal form of the nickel-based superalloy may be used as a filler metal for welding a casting alloy, a wrought alloy, or a powder metal alloy or other wrought forms.

摘要： A method of manufacturing a nickel-based superalloy component includes providing or obtaining, in a powdered form, a build material alloy including, on a weight basis of the overall build material alloy: about 9.5% to about 10.5% tungsten, about 9.0% to about 11.0% cobalt, about 8.0% to about 8.8% chromium, about 5.3% to about 5.7% aluminum, about 2.8% to about 3.3% tantalum, about 0.3% to about 1.6% hafnium, about 0.5% to about 0.8% molybdenum, about 0.005% to about 0.04% carbon, and a majority of nickel. The method further includes subjecting the build material alloy to a high energy density beam in an additive manufacturing process to selectively fuse portions of the build material to form a built component and subjecting the built component to a finishing process to precipitate a gamma-prime phase of the nickel-based superalloy.

摘要： Methods for manufacturing an article include providing a three-dimensional computer model of the article and providing a metal alloy in powdered form. The metal alloy is an aluminum-iron-vanadium-silicon alloy. The powdered form includes a grain size range of about 5 to about 22 microns and a d50 grain size average of about 10 to about 13 microns. The methods further include, at a binder jet printing apparatus, supplying the metal alloy and loading the three-dimensional model, and, using the binder jet printing apparatus, manufacturing the article in accordance with the loaded three-dimensional model in a layer-by-layer manner with the supplied metal alloy. A liquid binder is applied at each layer, and each layer has a thickness of about 10 to about 150 microns. The methods avoid remelting of the metal alloy and avoid metal alloy cooling rates of greater than about 100° F. per minute.

摘要： A coupling apparatus for use in sealingly connecting a first fluid flow path to a second fluid flow path. The coupling apparatus includes a rigid fluid flow channel having a first end and a second end, wherein the fluid flow channel is substantially rigid in an axial direction and a radial direction, a first sealing terminus that is rigidly connected to the first end and that is configured for sealing with the first fluid flow path, and a second sealing terminus that is slidingly disposed about the second end such that the second sealing terminus is configured for relative movement with respect to the second end, and wherein the second sealing terminus is further configured for sealing with the second fluid flow path. The coupling apparatus further includes a flexible coupler connected to both the first sealing terminus and the second sealing terminus and surrounding the fluid flow channel, wherein the coupler is relatively more flexible in the axial direction and the radial direction as compared to the fluid flow channel.
