摘要： Methods of forming dispersoid hardened metallic materials are provided. In an exemplary embodiment, a method of producing dispersoid hardened metallic materials includes forming a starting composition with a base metal component and a dispersoid forming component. The starting composition includes the base metal component in an amount from about 50 to about 99.999 weight percent and the dispersoid forming component in an amount from about 0.001 to about 1 weight percent, based on the total weight of the starting composition. A starting powder is formed from the starting composition, and the starting powder is fluidized with a fluidizing gas for a period of time sufficient to oxidize the dispersoid forming component to form the dispersoid hardened metallic material. The dispersoid forming component is oxidized while the starting powder is a solid.
