Cam manufacturing process with submicrometric and / or nanometric grain structure and solid cross section.

摘要

Method of manufacturing cams with submicrometric and / or nanometric grain structure and solid cross-section. # The present invention relates to a method of manufacturing cams of solid cross-section with submicrometric and / or nanometric grain structure comprising the processing of preforms of a starting material by severe plastic deformation (SPD) by angular channel extrusion (ECAP), and the subsequent isothermal forging of said processed preform, by applying a forging stamping matrix configured to apply a certain geometry to the preform by forging. The cams obtained by the process of the invention have improved mechanical properties in terms of greater strength, hardness or toughness, as well as improved functional properties, derived from their submicrometric and / or nanometric structure. Likewise, its manufacture is carried out more easily due to the improvement in the forgeability of the materials to be stamped.
