Abstract

Procedimiento para reforzar un acero al carbono, caracterizado porque comprende las fases de: calentar rápidamente el acero al carbono para elevar la temperatura del acero en la regíon de la austenita a un régimen suficientemente para reducir al mínimo el desarrollo del grano de austenita, enfriar el acero al carbonato austenitizado para transformar el acero a una fina mezcla de ferrita proeutectoide acicular y un aglomerado eutectoide finamente dividido de ferrita y carburo de hierro, y elaborar el acero resultante para consolidar el acero.
