Abstract: Components and methods of processing such components from precipitation-strengthened alloys so that the components exhibit desirable grain sizes following a supersolvus heat treatment. The method includes consolidating a powder of the alloy to form a billet having an average grain size. The billet is then forged at a temperature below the solvus temperature to form a forging having an average grain size of not coarser than the grain size of the billet. The billet is then forged at a total strain of at least 5%, after which at least a portion of the forging is heat treated at a temperature below the solvus temperature to pin grains within the portion. The entire forging can then be heat treated at a temperature above the solvus temperature of the alloy without coarsening the grains in the portion.

Abstract: A system for use in additively manufacturing an object. The system includes a powder bed configured for containment within a build chamber, wherein the powder bed is formed from a mixture of a build material and a bonding agent. The system also includes a heat source configured to selectively heat the powder bed to a temperature such that the build material is at least partially sintered together by the bonding agent. The heat source also selectively heats the powder bed to the temperature that maintains the build material in a solid state.

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.
