Abstract

Se describen aceros al carbono de gran rendimiento que contienen una estructura de tres fases que consisten en granos de ferrita fusionados con granos que contienen estructuras de listones dislocados en los cuales listones de martensita se alteran con delgadas películas de austenita. La microestructura se puede formar mediante un singular método de austenización seguido por un enfriamiento en múltiples etapas de manera que prevenga la formación de bainita y perlita y la precipitación en las interfases entre las fases. Se puede obtener la microestructura deseada por fundición, tratamiento térmico, laminado en línea, forja u otros procedimientos de procesamiento metalúrgico comunes, y produce combinaciones superiores de propiedades mecánicas y de corrosión El proceso aquí descripto consiste en: formar una aleación que comprende Fe y por lo menos un elemento de aleación que comprende un máximo de 0,35% en peso de C en proporciones seleccionadas para otorgar a dicha aleación un rango de transición a martensita con una temperatura de inicio de por lo menos 300°C. Calentar dicha aleación para la austenización de la misma, en condiciones tales que se obtenga una fase de austenita homogénea con todos los elementos de aleación en solución. Enfriar dicha fase de austenita para transformar una porción a cristales de ferrita obteniendo una microestructura de dos fases (cristales de ferrita fusionados con cristales de austenita). Enfriar la microestructura a través del rango de transición a martensita para transformar los cristales de austenita a una microestructura que contiene listones de martensita y austenita retenida.
