Inventor: Branagan, Daniel J.  
Abstract: The invention includes a method of producing a hard metallic material by forming a mixture containing at least 55% iron and at least one of B, C, Si and P. The mixture is formed into an alloy and cooled to form a metallic material having a hardness of greater than about 9.2 GPa. The invention includes a method of forming a wire by combining a metal strop and a powder. The strip and the powder are rolled to form a wire containing at least 55% iron and from 2-7 additional elements including at lease one of C, Si and B. The invention also includes a method of forming a hardened surface on a substrate by processing a solid mass to form a power, applying the powder to a surface to forma a layer containing metallic glass, and converting the glass to a crystalline material having a nanocrystalline grain size. The invention includes a method of producing a hard metallic material by forming a mixture containing at least 55% iron and at least one of B, C, Si and P. The mixture is formed into an alloy and cooled to form a metallic material having a hardness of greater than about 9.2 GPa ...more ...less

Abstract: A method of making a tire mold segment with a porous metal tread surface for a tire mold wherein an annular segmental tire model of refractory material is formed with tire model segments which are used to shape and form each tire mold segment from powdered metal by applying heat and pressure to sinter the powdered metal as it is shaped by the tire model segment. Blades may be mounted in the tire model segments for transfer to the tire mold segments for molding slits a tire tread.
