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 article includes a substrate comprising a precipitate-strengthened alloy and a coating disposed over the substrate. The alloy comprises a) a population of gamma-prime precipitates, the population having a multimodal size distribution with at least one mode corresponding to a size of less than about 100 nanometers; or b) a population of gamma-double-prime precipitates having a median size less than about 300 nanometers. The coating comprises at least two elements, and further comprises a plurality of prior particles. At least a portion of the coating is substantially free of rapid solidification artifacts. Methods for fabricating the article and for processing powder useful for fabricating the article are also provided.

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: An analysis controller determines multi-dimensional characteristics of one or more corrosion pits in equipment. These characteristics can include depths, widths, and/or aspect ratios of the corrosion pits. The controller also determines one or more stresses on the equipment based on the characteristics of the corrosion that are determined. The analysis controller also generates a control signal to implement one or more remedial actions to one or more of remove the one or more corrosion pits, repair the equipment, or restrict operation of the equipment based on the one or more stresses that are determined.
