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 system and method described herein relate to applying an overlay metal-based coating to a metal-based substrate. An article is provided, which includes a metal-based substrate having an overlay metal-based coating disposed on the substrate at an interface. The interface is configured such that a crack formed within the overlay metal-based coating and approaching the interface has a propagation path that is more energetically favorable along the interface than through the interface and into the metal-based substrate.

Abstract: A method for preparing an improved article including a nickel-based superalloy is presented. The method includes heat-treating a workpiece including a nickel-based superalloy at a temperature above the 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 coprecipitate of a gamma-prime phase and a gamma-double-prime phase, wherein the gamma-prime phase of the coprecipitate has an average particle size less than 250 nanometers. An article having a minimum dimension greater than 6 inches is also presented. The article includes a material having a coprecipitate of a gamma-prime phase and a gamma-double-prime phase, wherein the gamma-prime phase of the coprecipitate has an average particle size less than 250 nanometers.
