Abstract: In accordance with an exemplary embodiment, a method of forming a oxide dispersion-strengthened alloy metal includes the steps of providing, in a powdered form, an oxide dispersion-strengthened alloy composition that is capable of achieving a dispersion-strengthened microstructure, directing a low energy density energy beam at a portion of the alloy composition, 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 about 106° F. per second, thereby forming the oxide dispersion-strengthened alloy metal.
