Abstract

Un método para preparar una plancha de acero con unamicroestructura compuesta predominantemente por formaciones de martensita templada de grano fino, ó de vainita inferior templada de grano fino, o por una mezcla de estás, en donde dicho método comprende los pasos de:(a) calentamiento de una pieza de acero a una temperatura de recalentamiento suficientemente alta como para: (i) homogeneizar sustancialmente dicha pieza de acero, (ii) disolver sustancialmente todos los carburos y carbonitruros de niobio y vanadio presentes en dicha pieza de acero, y (iii) establecer granos finos iniciales de austenita en dicha pieza de acero;(b) reducción de dicha pieza de acero a fin de formar una plancha de acero en uno o más pasos por rodillos calientes en un primer rango de temperaturas dentro del cual la austenita se recristaliza;(c) reducción adicional de dicha plancha de acero en uno o más pasos por rodillos calientes en un segundo rango de temperaturas ubicadas por debajo de latemperatura Tnr (Temperatura por debajo de la cual la austenita no se recristaliza) y por encima de la temperatura de transformación Ar3 ; (Temperatura a la cual la austenita comienza a transformarse en ferrita durante el enfriamiento.(d) enfriamiento rápido de dicha plancha de acero a una velocidad de enfriamiento situada entre 10°C por segundo y 40°C por segundo (18°F/seg - 72°F/seg) a una Temperatura de Detención del Enfriamiento Rápido inferior a la temperatura de transformación Ms más 200°C (360°F);(e) detención de dicha operación de enfriamiento rápido; y(f) templado de dicha plancha de acero a una temperatura situada entre 400°C (752°F) y la temperatura de transformación Ac1 (Temperatura a la cual la austenita comienza a formarse durante el calentamiento) durante un período de tiempo suficiente para provocar la precipitación de partículas comunicadoras de endurecimiento, y así facilitar la transformación de dicha microestructura de dicha plancha de acero en una microestructura compuesta predominantemente por formaciones de martensita templada de grano fino, o de vainita inferior templada de grano fino, o por una mezcla de estás.
