Abstract

Un método para procesar una hoja de acero de fase doble. El método incluye calentar la hoja de acero a una primera temperatura (T1), enfriar la hoja de acero a una segunda temperatura (T2), hacer la transición de la hoja de acero a una tercera temperatura (T3), y enfriar la hoja de acero a temperatura ambiente. T1 está por lo menos por encima de la temperatura a la cual la hoja de acero se transforma a austenita y ferrita. T2 es menor a la temperatura de inicio de martensita (Ms). La tasa de enfriamiento a T2 es suficientemente rápida para transformar al menos alguna austenita en martensita.
