Abstract
A method for manufacturing a wrought metallic article from a metallic-powder composition includes steps of: consolidating the metallic-powder composition to yield a consolidated preform having a cross-sectional area and a relative density of less than 100 percent; reducing the cross-sectional area of the consolidated preform via at least one forming pass of one of a cogging process and a rotary incremental forming process, thereby yielding an intermediate preform; and reducing the cross-sectional area of the intermediate preform via at least one forming pass of another of the cogging process and the rotary incremental forming process.
