    摘要: Methods of forming dual microstructure components include consolidating a powder material comprising an alloy to form a billet, the billet having a first grain structure, inductively heating the billet at an inductive heat treat temperature above a gamma prime solvus temperature of the alloy and subjecting the billet to a subsolvus heat treat temperature that is below the gamma prime solvus temperature of the alloy, waiting a period of time for the first grain structure in an outer portion of the billet to transform into a second grain structure that is coarser than the first grain structure, after the steps of inductively heating and subjecting the billet to the subsolvus heat treat temperature. The methods also include dividing the billet into at least two sections, and machining a final shape into one or more of the at least two sections to form the dual microstructure component.

    摘要: Apparatus and compositions for a turbine disk capable of sustained operation at turbine disk rim temperatures in excess of 1300° F., wherein the turbine disk comprises a superalloy substrate, and a ductile oxidation barrier coating disposed on at least an outer portion of the turbine disk. The oxidation barrier coating may comprise a ductile metal, such as platinum, palladium, or platinum alloyed with Al, Cr, Ni, Pd, Ti, or Zr. Methods for providing an oxidation barrier-coated turbine disk are also disclosed.

    摘要: Methods are provided for manufacturing turbine disks each having a hub surrounded by a rim, the hub having a first microstructure and the rim having a second microstructure that is coarser than the first microstructure, the methods employing a first powder alloy having a first gamma prime solvus temperature and a second powder alloy having a second gamma prime solvus temperature that is less than the first gamma prime solvus temperature. One method includes the steps of forming an ingot from the first and second powder alloys, the ingot having an inner section having the first microstructure and an outer section having a microstructure that is less coarse than the second microstructure, and exposing the ingot to a temperature between the first and second gamma prime solvus temperatures while forming the ingot into a plurality of turbine disks to transform the microstructure of the outer section into the second microstructure.
