Abstract

Cuando una zona rodeada por un límite de grano que se mide como 5.0° o más por un análisis de EBSD se supone que es un grano, y cuando un valor K es un valor obtenido al multiplicar un valor promedio de calidad de imagen en un grano por 10-3, un valor Y es una desorientación de cristal promedio (°) en el grano, una fase metálica 1 es una fase metálica cuyo valor K es menor que 4.000, una fase metálica 2 es una fase metálica cuyo valor K es 4.000 o más y cuyo valor Y es de 0.5 a 1.0, una fase metálica 3 es una fase metálica cuyo valor K es 4.000 o más y el valor Y el cual es menos de 0.5, y una fase metálica 4 es una fase que no cae bajo ninguna de las fases metálicas 1 a 3, se proporciona una lámina de acero que tiene una composición química predeterminada e incluye una microestructura que incluye, en porcentaje de área, una fase metálica 1: 1.0% o más y menos de 35%, una fase metálica 2: 30.0% o más y 80.0% o menos, una fase metálica 3: 5.0% o más y 50.0% o menos, y una fase metálica 4: 5.0% o menos. La lámina de acero tiene una resistencia tan alta como 590 MPa o más (además, 780 MPa o más) en términos de resistencia a la tracción y tiene una excelente propiedad de expansión de huecos.
