Resumen
En las instalaciones de la empresa Trivium Packaging se fabricó una aleación experimental base Al-Mn-Mg cuyo objetivo es sustituir una de las actuales aleaciones utilizadas, igualando o superando sus propiedades tecnológicas y permitiendo el agregado de mayores porcentajes de scrap en la formulación. La aleación fue fabricada a partir de distintos parámetros de proceso de modo de obtener información del comportamiento mecánico de la aleación luego de atravesar distintas condiciones termomecánicas de proceso. Se realizaron ensayos de tracción, ensayos tecnológicos y se prepararon muestras metalográficas para analizar la microestructura obtenida, tanto de la aleación experimental como de la aleación actualmente utilizada. Posteriormente se analizaron comparativamente los resultados. Como método de obtención de propiedades relacionadas con la capacidad de la aleación de ser endurecida por deformación en frío se utilizó un ajuste a partir de la ecuación de la ley de Vose utilizando software desarrollado en Python. Se concluyó que la aleación se muestra prometedora a la hora de reemplazar a la aleación actualmente utilizada.
An experimental Al-Mn-Mg alloy was manufactured at Trivium Packaging company facilities, in aims to replace one of their current alloys used, matching or exceeding its technological properties and allowing the addition of higher percentages of scrap in the alloy formulation. The alloy was manufactured with different process parameters in order to obtain information on the mechanical behavior of the alloy after going through different thermomechanical processes. Tensile test and technological tests were performed, and metallographic samples were prepared to analyze the microstructure obtained, both for the experimental and currently used alloy. Subsequently, a comparative analysis was carried out. As a method to obtain properties related to the capacity of the alloy to be hardened by cold deformation, a Voce’s law equation fit was applied to the tensile test results by using software developed in Python. It was concluded that the alloy shows promise in replacing the currently used alloy.
