Abstract: A method for transient liquid phase bonding two metallic substrate segments together including the steps of forming a joined component by bringing together the two substrate segments along a bond line with a brazing alloy comprising a melting point depressant disposed between the two segments at the bond line and performing a first thermal treatment including heating the joined component at a brazing temperature of the brazing alloy for a first period of time. The method further includes performing a second thermal treatment including heating the joined component at an intermediate temperature that is above the brazing temperature but below a gamma prime solvus temperature of the substrate segments for a second period of time and performing a third thermal treatment including heating the joined component at a super-solvus temperature that is above the gamma prime solvus temperature of the two metallic substrate segments for a third period of time.

Abstract: Dual alloy turbine rotors and methods for manufacturing the same are provided. The dual alloy turbine rotor comprises an assembled blade ring and a hub bonded to the assembled blade ring. The assembled blade ring comprises a first alloy selected from the group consisting of a single crystal alloy, a directionally solidified alloy, or an equi-axed alloy. The hub comprises a second alloy. The method comprises positioning a hub within a blade ring to define an interface between the hub and the blade ring. The interface is a non-contacting interface or a contacting interface. The interface is enclosed by a pair of diaphragms. The interface is vacuum sealed. The blade ring is bonded to the hub after the vacuum sealing step.

Abstract: Embodiments of a turbine nozzle are provided, as are embodiments of methods for the manufacture of turbine nozzles. In one embodiment, the turbine nozzle includes a support ring and a slip joint ring, which is substantially concentric with the support ring and radially spaced apart therefrom. The slip joint ring has a plurality of slots therein. A plurality of vanes is fixedly coupled to the support ring and extends radially therefrom into the plurality of slots. A plurality of radial slip joints is formed between the plurality of vanes and the plurality slots. Each slip joint extends around a different one of the plurality of vanes to permit relative radial movement between the plurality of vanes and the slip joint ring during operation of the turbine nozzle.

Abstract: Methods for processing bonded dual alloy rotors are provided. In one embodiment, the method includes obtaining a bonded dual alloy rotor including rotor blades bonded to a hub disk. The rotor blades and hub disk are composed of different alloys. A minimum processing temperature (TDISK_PROCESS_MIN) for the hub disk and a maximum critical temperature for the rotor blades (TBLADE_MAX) is established such that TBLADE_MAX is less than TDIsK_PROCESS_MIN. A differential heat treatment process is then performed during which the hub disk is heated to processing temperatures equal to or greater than TDISK_PROCESS_MIN, while at least a volumetric majority of each of the rotor blades is maintained at temperatures below TBLADE_MAX. Such a targeted differential heat treatment process enables desired metallurgical properties (e.g., precipitate hardening) to be created within the hub disk, while preserving the high temperature properties of the rotor blades and any blade coating present thereon.

Abstract: Methods of forming dispersoid hardened metallic materials are provided. In an exemplary embodiment, a method of producing dispersoid hardened metallic materials includes forming a starting composition with a base metal component and a dispersoid forming component. The starting composition includes the base metal component in an amount from about 50 to about 99.999 weight percent and the dispersoid forming component in an amount from about 0.001 to about 1 weight percent, based on the total weight of the starting composition. A starting powder is formed from the starting composition, and the starting powder is fluidized with a fluidizing gas for a period of time sufficient to oxidize the dispersoid forming component to form the dispersoid hardened metallic material. The dispersoid forming component is oxidized while the starting powder is a solid.

Abstract: A method of manufacturing a directionally solidified article of the present disclosure includes providing a collection of particulate material and additively manufacturing a first article with an outer wall from the particulate material. The outer wall defines at least part of a cavity. The cavity contains an amount of the particulate material. The method also includes encasing at least a portion of the first article with an outer member. The outer member defines an internal cavity that corresponds to the first article. The method further includes heating the outer member and the first article to melt the first article into a molten mass within the internal cavity of the outer member. Additionally, the method includes solidifying the molten mass along a predetermined solidification path within the outer member to form a second article that corresponds to at least a portion of the internal cavity of the outer member.
