Resumen


En este estudio, se evaluó el efecto de la técnica de presión calibrada, sobre las propiedades mecánicas y la microestructura de probetas de acero inoxidable AISI 316L, hasta lograr una deformación equivalente de ε~4,64. Dicha evaluación se realizó antes y después de aplicar la deformación plástica. Los resultados obtenidos mostraron un aumento en la dureza, el límite elástico y la resistencia útima a la tracción debido a la reducción del tamaño de grano, el maclado de mecánico y la transformación martensítica.
