Abstract
The invention relates to a method for heat treating a workpiece by using at least one heat transfer liquid. The method includes the steps of placing a workpiece inside an oven that forms an internal cavity that is hermetically sealable, setting the oven at a temperature that is suitable for enabling a fraction of vapor of the heat transfer liquid to condense on the workpiece, introducing vaporized heat transfer liquid into the oven, allowing a fraction of the vapor to condense onto the workpiece, extracting the remaining vapor from the oven, and removing the workpiece from the oven.
