La tensión umbral para la fluencia, en un material de base magnesio

Abstract

Se ha estudiado la presencia de una tensión umbral, en una aleación de magnesio AZ31 de pequeño tamaño de grano conteniendo diferentes cantidades de partículas, procesada por métodos pulvimetalúrgicos. Se observó que el deslizamiento en fronteras de grano es el mecanismo que controla la deformación, en un intervalo amplio de velocidades de deformación y temperaturas. La disminución drástica de la velocidad de deformación, con una pequeña disminución de la tensión, permite deducir la presencia de una tensión umbral. Esta tensión umbral es independiente de la temperatura. En este trabajo se hace un análisis de su presencia y de su dependencia con los parámetros estructurales y mecánicos de las aleaciones

Se agradece a la CICYT por la financiación de este trabajo a través del Proyecto MAT2009-14452
