Abstract
Un objetivo de la presente invención es proporcionar una lámina de acero laminada en frío de alta resistencia que tiene una tensión de rotura TS de 1180 Mpa o más obtenida mediante la preparación de una estructura metalográfica en un sistema de componentes libre de elementos de aleación caros, mejorando de ese modo las propiedades de elongación, abocardabilidad, y doblado de la lámina de acero. Con el fin de lograr el objetivo, la lámina de acero de la presente invención tiene una composición química específica, y una microestructura que incluye fase de ferrita: 40% a 60%, fase de bainita: 10% a 30%, fase de martensita revenida: 20% a 40%, y fase de austenita retenida: 5% a 20% en fracción en volumen, y que satisface una condición de que una relación de fase de martensita revenida que tiene una longitud de eje principal = 5 µm a una fracción en volumen total de la fase de martensita revenida es de 80% a 100%.
