Abstract: Methods and apparatuses for obtaining bainite are disclosed. The method includes heating a metal component in a vacuum chamber of a vacuum furnace to raise an internal temperature of the metal component, transferring the metal component from the vacuum chamber to a quench chamber of the vacuum furnace, quenching the metal component in oil that is maintained at a bainite-forming temperature range within a quench reservoir of the quench chamber, and removing the metal component from the quench chamber after a predetermined period of time.
