    Abstract: A method for preparing an article including a nickel-based superalloy is presented. The method includes heat-treating a workpiece including a nickel-based superalloy at a temperature above a gamma-prime solvus temperature of the nickel-based superalloy and cooling the heat-treated workpiece with a cooling rate less than 50 degrees Fahrenheit/minute from the temperature above the gamma-prime solvus temperature of the nickel-based superalloy so as to obtain a cooled workpiece. The cooled workpiece includes a gamma-prime precipitate phase having an average particle size less than 250 nanometers at a concentration of at least 10 percent by volume, and is substantially free of a gamma-double-prime phase. An article having a minimum dimension greater than 6 inches is also presented. The article includes a material that has a gamma-prime precipitate phase having an average particle size less than 250 nanometers, and is substantially free of a gamma-double-prime phase.

    Abstract: An electroformed composite component includes reinforcing particles in a metal matrix. The composite component is formed by a method including passing an electric current between an anode and a cathode in the presence of an electrolyte. The electrolyte includes a metal salt and a plurality of reinforcing particle precursors. The method further includes depositing a composite layer on the cathode, wherein the composite layer includes the metal matrix and the plurality of reinforcing particle precursors dispersed in the metal matrix. An optional heat treatment can be performed subsequently to transform the precursor particles to more stable forms with concomitant improvement in composite material properties.

    Abstract: A corrosion maintenance scheduling and implementation system and method measure one or more characteristics of corrosion in equipment before and after implementation of a corrosion remediation action, determine one or more of a change in the one or more characteristics of the corrosion between before and after implementation of the corrosion remediation action, one or more historical operational characteristics of the equipment, or one or more forthcoming operational characteristics of the equipment, and modify a schedule of the corrosion remediation action for the equipment based on one or more of the one or more characteristics of corrosion that are measured, the change in the one or more characteristics of the corrosion, the one or more historical operational characteristics of the equipment, and/or the one or more forthcoming operational characteristics of the equipment.

    Abstract: A method of forming a component by an electroforming process using an electroforming apparatus is presented. The electroforming apparatus includes an anode, a cathode and an electrolyte including a metal salt. The method includes receiving a set of training electroforming process parameters; training a machine learning algorithm based on at least a subset of the set of training electroforming process parameters; generating a set of updated operating electroforming parameters from the trained machine learning algorithm; and operating the electroforming apparatus based on the set of updated operating electroforming parameters. The step of operating the electroforming apparatus includes applying an electric current between the anode and the cathode in the presence of the electrolyte and depositing a plurality of metal layers on a cathode surface to form the component. A system of forming a component is also presented.
