A method for heat treating an additively manufactured A205 aluminum alloy component ('AM205 component') to produce a uniform grain distribution within the AM205 component is disclosed. The method includes solution aging the AM205 component at a first temperature for a first time period, wherein the first time period is less than five hours and overaging the AM205 component after the solution aging.

The present disclosure provides methods of forming products using one or more lasers. In at least one aspect, a method for powder bed additive manufacturing includes defining a uniform pitch raster path for a laser traveling at a predetermined rate of travel. The raster path alternates back and forth within a strip width of less than 0.5 mm such that the laser's power density level is at least 80 percent of maximum power and the predetermined rate of travel yields a travel speed in the scan width direction of not less than 1,000 mm/s. The method includes depositing a layer of powder onto a substrate and causing the laser to solidify a quantity of the powder according to the defined raster path and the laser power setting.
