description In the present patent a novel method is proposed for obtaining materials with improved mechanical properties, as a consequence of their processing through an angular or polyangular channel, which enables both the severe plastic deformation of volumetric elements and slender parts, without modification significant of the cross-sectional shape of the same. The proposed process presents the novelty of combining a hydraulic system for obtaining a hydrostatic pressure in the fluid capable of generating the necessary pressure to perform the extrusion of materials through an extrusion matrix in angular or polyangular channel, resulting in the cross section of the processed material is substantially equal to that of the starting material. With the present invention, the buckling problems associated with the traditional angular channel extrusion processes are avoided. (Machine-translation by Google Translate, not legally binding) En la presente patente se propone un método novedoso para la obtención de materiales con propiedades mecánicas mejoradas, como consecuencia de su procesamiento a través de un canal angular o poliangular, que posibilita tanto la deformación plástica severa de elementos volumétricos como de piezas esbeltas, sin modificación significativa de la forma de la sección transversal de las mismas. El proceso que se propone presenta la novedad de combinar un sistema hidráulico para la obtención de una presión hidrostática en el fluido capaz de generar la presión necesaria para realizar la extrusión de materiales a través de una matriz de extrusión en canal angular o poliangular, resultando que la sección transversal del material procesado es sustancialmente igual a la del material de partida. Con la presente invención se evitan los problemas de pandeo asociados a los procesos tradicionales de extrusión en canal angular.
