Abstract
Un elemento de acero que tiene buenas propiedades de resistencia al crecimiento de grietas por fatiga en un rango de deformacion plastica, una lamina de acero laminada en caliente para usar como material del mismo, y se proporcionan sus metodos de produccion. Un elemento de acero contiene, en porcentaje en masa, de 0.010% a 0.120% de Ti, en el que se precipita 0.005% o mas de Ti como un precipitado que tiene un tamano de particula de 20 nm o menos en la microestructura. Una lamina de acero laminada en caliente para el elemento de acero contiene, en porcentaje en masa, de 0.010% a 0.120% de Ti, en el que 0.005% o mas de Ti esta presente como Ti disuelto en la microestructura. Un metodo para producir el elemento de acero incluye someter una lamina de acero laminada en caliente a un proceso de formacion y luego realizar un tratamiento termico que incluye el calentamiento a una temperatura superior a 550°C y 1,050°C o inferior y despues enfriar a una tasa de enfriamiento promedio de 10°C/s o mas en el rango de temperatura de 550°C a 400°C. Un metodo para producir la lamina de acero laminada en caliente incluye despues de realizar la extraccion de la lamina de una lamina de acero que contiene, en porcentaje en masa, de 0.010% a 0.120% de Ti a una temperatura mas alta que una temperatura de disolucion de equilibrio TTi calculada a partir de una formula predeterminada, completar el laminado de acabado a una temperatura igual o superior a TTi - 400°C, realizar enfriamiento a una tasa de enfriamiento de 10°C/s en promedio o mas en el rango de temperatura de TTi - 400°C a TTi - 500°C, y realizar enrollamiento a una temperatura igual o inferior a TTi - 500°C.
