20170297081 · 2017-10-19 · ·

A method for production of a metallic material from a semifinished metallic billet, the semifinished metallic billet including a nanocrystalline microstructure and/or an ultrafine-grained microstructure, the method including the steps of (1) subjecting the semifinished metallic billet to a rotary incremental forming process to form an intermediate wrought metallic billet, and (2) subjecting the intermediate wrought metallic billet to a high rate forming process to form a metallic product.

WROUGHT METALLIC ARTICLE AND METHOD FOR MANUFACTURING THE SAME FROM A METALLIC-POWDER COMPOSITION

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.
