Abstract
A method for making an article is disclosed. The method involves inputting a digital model of an article into an additive manufacturing apparatus comprising an energy source. The additive manufacturing apparatus applies energy from the energy source to successively applied incremental quantities of a powder to fuse the powder to form the article corresponding to the digital model. The powder includes an aluminum alloy having 2.00-10.00 wt. % cerium, 0.50-2.50 wt. % titanium, 0-3.00 wt. % nickel, 0-0.75 wt. % nitrogen, 0-0.05 wt. % other alloying elements, and the balance of aluminum, based on the total weight of the aluminum alloy.
