Abstract

Los objetivos son proporcionar una chapa de acero de alta resistencia que tiene una TS de 1320 MPa o más y un El de 8% o más y que tiene una amplia gama de espacios libres apropiados para la deformación por expansión de orificio y una amplia gama de espacios libres apropiados que no conducen a fractura retardada; y proporcionar un método para fabricar la misma. Una chapa de acero de alta resistencia incluye una microestructura específica que tiene una composición química específica y que satisface las fórmulas (1) y (2) definidas más abajo: KAM (S)/KAM (C) < 1.00 ·····(1) donde KAM (S) es un valor de KAM (desorientación promedio del Núcleo) de una porción superficial de la chapa de acero y KAM (C) es un valor de KAM en una porción central de la chapa de acero, Hv (Q) - Hv (S) = 8 ·····(2) donde Hv (Q) indica la dureza de una porción en 1/4 del espesor de la chapa y Hv (S) indica la dureza de una porción superficial de la chapa de acero.
