Abstract
A method of forming a component includes providing a work-piece blank from a formable material. The work-piece blank includes at least one section having a surface roughness greater than 1 μm configured to facilitate efficient radiation of thermal energy therefrom when the work-piece blank is heated. The method also includes austenitizing the work-piece blank via heating the work-piece blank at a predetermined temperature for a predetermined amount of time to achieve an austenite microstructure in the at least one section and forestall oxidation of the work-piece blank. The method additionally includes transferring the austenitized work-piece blank into a forming press. The method also includes forming the component via the forming press from the austenitized work-piece blank. The method additionally includes quenching the component formed from the austenitized work-piece blank and cooling the formed component.
