Abstract
A method for manufacturing a wrought metallic article from metallic-powder compositions comprises steps of (1) compacting the metallic-powder composition to yield a compact, having a surface, a cross-sectional area, and a relative density of less than 100 percent, (2) reducing the cross-sectional area of the compact via an initial forming pass of a rotary incremental forming process so that the compact has a decreased cross-sectional area, and (3) reducing the decreased cross-sectional area of the compact via a subsequent forming pass of the rotary incremental forming process by a greater percentage than that, by which the cross-sectional area of the compact was reduced during the initial forming pass.
