Abstract:
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.
