Abstract
A metallic material manufactured by a method including steps of (1) subjecting a semifinished metallic billet having at least one of a nanocrystalline microstructure and an ultrafine-grained microstructure 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, wherein the high rate forming process includes a high rate forming process average equivalent strain rate, the high rate forming process average equivalent strain rate being at least about 0.1 s−1.

A metallic material manufactured by a method comprising:
- subjecting a semifinished metallic billet comprising at least one of a nanocrystalline microstructure and an ultrafine-grained microstructure to a rotary incremental forming process to form an intermediate wrought metallic billet;
- and
- subjecting said intermediate wrought metallic billet to a high rate forming process, wherein said high rate forming process comprises a high rate forming process average equivalent strain rate, said high rate forming process average equivalent strain rate being at least about 0.1 s−1.
A 6061 aluminum alloy composition comprising aluminum, magnesium, silicon, copper, and chromium, wherein, as annealed, the aluminum alloy composition has an ultimate tensile strength of at least 30 ksi.
