Claim Text:
1. A method of forming an oxide dispersion-strengthened alloy metal comprising the steps of: providing, in a powdered form, an oxide dispersion-strengthened alloy composition that is capable of achieving a dispersion-strengthened microstructure, wherein providing the oxide dispersion-strengthened alloy composition in powdered form comprises mixing a plurality of metals and oxides forming the alloy to form a mixture, melting the mixture to form a melted mixture, and atomizing the melted mixture into the powdered form; directing a low energy density energy beam at a portion of the alloy composition, wherein the portion of the alloy composition is provided in a layer having a thickness of less than 0.025 mm; withdrawing the energy beam from the portion of the powdered alloy composition; and cooling the portion of the powdered alloy composition at a rate greater than or equal to 10
