Abstract

Procedimiento de fabricación de elementos mecánicos de geometría hueca con estructura submicrométrica o nanométrica.#La presente invención se refiere a un procedimiento de fabricación de elementos mecánicos de estructura de grano submicrométrica y/o nanométrica, que tienen geometría interior hueca, y denominados de forma genérica como anillos. Dicho procedimiento comprende, preferentemente, el procesado de preformas de un material de partida mediante deformación plástica severa (SPD) por extrusión en canal angular (ECAE), y el posterior forjado isotérmico de dicha preforma procesada, mediante la aplicación de una matriz de estampación de forjado configurada para aplicar una geometría hueca a la preforma mediante su forjado. Los elementos mecánicos obtenidos mediante el procedimiento de la invención presentan propiedades mecánicas mejoradas en cuanto a mayor resistencia, dureza o tenacidad, así como propiedades funcionales mejoradas, derivadas de su estructura submicrométrica y/o nanométrica.Method of manufacturing mechanical elements of hollow geometry with submicrometric or nanometric structure. # The present invention relates to a method of manufacturing mechanical elements of submicrometric and / or nanometric grain structure, which have hollow interior geometry, and generically denominated. like rings Said process preferably comprises the processing of preforms of a starting material by severe plastic deformation (SPD) by angular channel extrusion (ECAE), and the subsequent isothermal forging of said processed preform, by the application of a stamping matrix of Forged configured to apply a hollow geometry to the preform by its forging. The mechanical elements 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 its submicrometric and / or nanometric structure.
