  • METHOD FOR MANUFACTURING A PART MADE OF A MONOCRYSTALLINE SUPERALLOY
    Publication number: 20220243312
    Abstract: The invention concerns a method for manufacturing an aircraft part, the part comprising a monocrystalline nickel-based superalloy substrate, the method consecutively implementing the steps of moulding the part at a moulding temperature greater than the melting temperature of the superalloy, and cooling the part, such that the monocrystalline superalloy has a ? phase and a ? phase, solution heat treatment of the part at a first temperature between the solves temperature of the ?? phase and the melting temperature of the superalloy, homogenising the crystalline structure or the part, cooling the part to ambient temperature, first tempering and second tempering.

  • Ni-based superalloy part recycling method
    Patent number: 10689741
    Abstract: A method for recycling a Ni-based single crystal superalloy part or unidirectionally solidified superalloy part provided with a thermal barrier coating containing at least a ceramic on a surface of a Ni-based single crystal superalloy substrate or Ni-based unidirectionally solidified superalloy substrate, in which the method including the steps of: melting and desulfurizing a Ni-based single crystal superalloy part or Ni-based unidirectionally solidified superalloy part at a temperature of the melting point or more of the Ni-based single crystal superalloy or Ni-based unidirectionally solidified superalloy and less than the melting point of the ceramic; heating a casting mold for a recycled Ni-based single crystal superalloy part or casting mold for a recycled Ni-based unidirectionally solidified superalloy part to a temperature of the melting point or more of the Ni-based single crystal superalloy or Ni-based unidirectionally solidified superalloy; pouring the desulfurized melted Ni-based single crystal supe
