Abstract
Una lámina de acero de alta resistencia incluye una composición química que incluye: en % en masa, C: 0.080 a 0.500%, Si: 2.50% o menos, Mn: 0.50 a 5.00%, P: 0.100% o menos, S: 0.0100% o menos, Al: 0.001 a 2.500%, N: 0.0150% o menos, O: 0.0050% o menos, y el resto: Fe e impurezas inevitables. La lámina de acero de alta resistencia que satisface una fórmula predeterminada tiene una microestructura en una región de 1/8t a 3/8t desde la superficie de la lámina de acero. La microestructura incluye: en % en volumen, 20% o más de ferrita acicular, 20% o más de una estructura dura en forma de isla que incluye austenita residual, 2% a 25% de austenita residual y 20% o menos de ferrita agregada. En la estructura dura con forma de isla, una relación de aspecto promedio de una región dura que tiene un diámetro circular equivalente de 1.5 µm o más es de 2.0 o más, una relación de aspecto promedio de una región dura que tiene un diámetro circular equivalente de menos de 1.5 µm es menor que 2.0, un promedio de una densidad numérica de la región dura que tiene un diámetro circular equivalente de menos de 1.5 µm es igual o mayor que 1.0 × 1010 piezas·m-2.y una relación entre una densidad numérica máxima y una densidad numérica mínima es 2.5 o menos.
