Abstract

Un método para preparar una lámina de fase doble que tiene unamicroestructura que comprende aproximadamente 10% en volumen a 40% en volumen de una primera fase de esencialmente ferrita y 60% en volumen a 90% en volumen de una segunda fase de predominantemente martensita en placa de grano fino, bainita inferior de grano fino, o mezclas de estas, en donde dicho método comprende los pasos de: a) calentamiento de una placa de acero hasta una temperatura de recalentamiento lo suficientemente alta para (i) homogeneizar sustancialmente dicha placa de acero, (ii) disolver sustancialmente todos los carburos y carbonitruros de niobio y vanadio en dicha placa de acero, y (iii) establecer finos granos de austenita inicial en dicha placa de acero; (b) reducir dicha placa de acero hasta formar lámina de acero en uno o más pases de laminado en caliente en un primer rango de temperatura en el cual recristaliza la austenita; (c) reducción adicional de dicha lamina de acero en uno o más pases de laminado en caliente en un segundo rango de temperatura por debajo de la temperatura de Tnr (Temperatura por debajo de la cual la austenita no se recristaliza) y por encima de la temperatura de transformación Ar3 ; (Temperatura a la cual la austenita comienza a transformarse a ferrita durante el enfriamiento). (d) reducción adicional de dicha lámina de acero en uno o más pases de laminado en caliente en un tercer rango de temperatura entre la temperatura de transformación Ar3 (Temperatura a la cual la austenita comienza a transformarse a ferrita durante el enfriamiento) y la temperatura de transformación Ar1 (Temperatura a la cual se completa la transformación de austenita a ferrita o ferrita más cementita durante el enfriamiento).
