Abstract
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 106° C. per second, thereby forming the dispersion-strengthened aluminum alloy metal.

A method of forming a dispersion-strengthened aluminum alloy metal comprising the steps of:
- providing, in a powdered form, an aluminum alloy composition that is capable of achieving a dispersion-strengthened microstructure;
- directing a low energy density laser beam at a portion of the alloy composition;
- withdrawing the laser 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° C. per second, thereby forming the dispersion-strengthened aluminum alloy metal.
A method of forming a dispersion-strengthened capable aluminum alloy component comprising the steps of:
- providing an Al—Fe—V—Si aluminum alloy composition in a powdered form;
- providing a three-dimensional design for the component;
- and
- subjecting the powdered alloy composition to an additive manufacturing procedure that employs a low energy density laser beam, wherein the additive manufacturing procedure is performed in accordance with the three-dimensional design.
