Abstract

Una lámina de acero de alta resistencia con excelente conformabilidad y alto límite de elasticidad y conformabilidad por expansión de agujero que tiene TS de 590 MPa o más y YR de 68% o más se obtiene al proporcionar una composición química predeterminada y una microestructura de acero que contiene, en relación de área, 20% o más y 65% o menos de ferrita poligonal, 8% o más de ferrita no recristalizada, y 5% o más y 25% o menos de martensita, y que contiene, en fracción de volumen, 8% o más de austenita retenida, donde una relación de aspecto promedio de granos de cristal de cada fase (ferrita poligonal, martensita, y austenita retenida) es de 2.0 o más y 15.0 o menos, en donde la ferrita poligonal tiene un tamaño de grano promedio de 6 µm o menos, la martensita tiene un tamaño de grano promedio de 3 µm o menos, la austenita retenida tiene un tamaño de grano promedio de 3 µm o menos, y un valor obtenido al dividir un contenido de Mn en la austenita retenida en % en masa entre un contenido de Mn en la ferrita poligonal en % en masa es igual a 2.0 o más.
