Abstract

Se proporciona: una lámina de acero laminada en frío de alta resistencia que tiene una resistencia a la tensión de 980 MPa o mayor, que tiene una buena capacidad de formación según se evalúa por ductilidad y capacidad de formar brida por tensión, y que tiene una excelente resistencia al choque; y un método para producir la lámina de acero. En esta lámina de acero laminada en frío de alta resistencia, la estructura metálica en una posición de 1/4 del espesor de la lámina satisface (1) a (4) a continuación. (1) La proporción de área de ferrita es más de 10% a 65% o menos, con el balance que es una fase dura que incluye martensita enfriada y austenita retenida y que incluye al menos uno seleccionado del grupo que consiste en ferrita bainítica, bainita y martensita templada. (2) La proporción volumétrica V? de la austenita retenida es 5% o más hasta 30% o menos. (3) La proporción de área VMA de una estructura MA en la que se combinan martensita enfriada y austenita retenida es 3% o más hasta 25% o menos y el diámetro equivalente a un de círculo promedio de la estructura MA es 2.0 µm o menos. (4) La proporción VMA\V? de la proporción de área VMA de la estructura MA a la proporción volumétrica V? de la austenita retenida es 0.50 a 1.50.It is provided: a high-strength cold-rolled steel sheet that has a tensile strength of 980 MPa or greater, that has a good formability as assessed by ductility and ability to form tension flange, and that has a excellent shock resistance; and a method to produce the steel sheet. In this high strength cold rolled steel sheet, the metal structure in a position of 1/4 of the thickness of the sheet satisfies (1) to (4) below. (1) The proportion of ferrite area is more than 10% to 65% or less, with the balance being a hard phase that includes chilled martensite and retained austenite and that includes at least one selected from the group consisting of bainitic ferrite, Bainite and temperate martensite. (2) The volumetric ratio V? of retained austenite is 5% or more up to 30% or less. (3) The proportion of VMA area of an MA structure in which cooled martensite and retained austenite are combined is 3% or more up to 25% or less and the diameter equivalent to an average circle of the MA structure is 2.0 µm or less . (4) The VMA \ V ratio? from the proportion of area VMA of the structure MA to the volumetric proportion V? of retained austenite is 0.50 to 1.50.
