| Zusammenfassung: | In accordance with an exemplary embodiment, a method of forming a dispersion-strengthened aluminum alloy metal includes the steps of providing a dispersion-strengthened aluminum alloy composition in a powdered form, directing a low energy density laser beam at a portion of the powdered alloy composition, and withdrawing the laser beam from the portion of the powdered alloy composition. Subsequent to withdrawal of the laser beam, the portion of the powdered alloy composition cools at a rate greater than or equal to about 10 6 °C per second, thereby forming the dispersion-strengthened aluminum alloy metal. |
