Evaluation of the Corrosion Resistance of AISI 316l Steel Subjected to Severe Deformation Using the Groove Pressing Technique
In this investigation, samples of AISI 316L steel were subjected to severe plastic deformation by the groove pressing (GP) technique using 2 dies A2 type tool steel dies with dimensions of 96 mm X 96 mm, a corrugated die with 2 mm teeth and 45° angle and a flat die. Each pass through the GP die incl...

| description | In this investigation, samples of AISI 316L steel were subjected to severe plastic deformation by the groove pressing (GP) technique using 2 dies A2 type tool steel dies with dimensions of 96 mm X 96 mm, a corrugated die with 2 mm teeth and 45° angle and a flat die. Each pass through the GP die includes 2 states of corrugated and 2 states of straightening with a 180° rotation between each of them. This configuration provides the material with an equivalent theoretical deformation per pass of ε~1.16. The material was deformed by 4 passes per GP to an equivalent deformation of ε~4.64. Prior to the deformation, the specimens were subjected to an annealing heat treatment for 1 hour at 1000 °C with water cooling, in order to eliminate the lamination texture. The annealed and deformed material was characterized chemically and microstructurally by X-ray fluorescence and scanning electron microscopy, respectively. In order to evaluate the corrosion behavior of the material, linear polarization resistance and analysis by Tafel plot were used in a 0.6 M NaCl solution for 0 and 24 hours. The results show an atypical behavior regarding the corrosion resistance of AISI 316L steel. An increase in corrosion resistance of 45% of the material was observed after 4 passes per GP compared to annealed material (0 passes). |

En esta investigación, muestras de acero AISI 316L fueron sometidas a deformación plástica severa por la técnica presión calibrada (GP) mediante el uso de 2 matrices de acero de herramientas tipo A2 con dimensiones de 96 mm X 96 mm, una matriz corrugada con dientes de 2 mm y ángulo de 45° y una matriz plana. Cada pase por la matriz GP incluye 2 estados de corrugado y 2 estados de enderezado con una rotación de 180° entre cada uno de ellos. Esta configuración provee al material una deformación teórica equivalente por pase de ε~1.16. Al material fue deformado por 4 pases por GP hasta una deformación equivalente de ε~4,64. Previo a la deformación, las probetas fueron sometidas a un tratamiento térmico de recocido durante una 1 hora a 1000 °C con enfriamiento en agua, con el fin de eliminar la textura de laminación. El material en estado de recocido y deformado se caracterizó química y microestructuralmente mediante fluorescencia de rayos X y microscopía electrónica de barrido, respectivamente. Con el fin de evaluar el comportamiento a la corrosión del material, se utilizó la resistencia a la polarización lineal y el análisis mediante las curvas de Tafel en una solución de 0,6 M de NaCl por un tiempo de 0 y 24 horas. Los resultados muestran un comportamiento atípico en cuanto a la resistencia a la corrosión del acero AISI 316L. Se observó un aumento en la resistencia a la corrosión del 45% del material después de 4 pases por GP en comparación con el material recocido (0 pases).
