ABSTRACT:
A hybrid furnace includes a vacuum furnace for heat treating a workpiece and a transportable oven removably attached to the vacuum furnace for holding the workpiece and maintaining it at an elevated temperature. The workpiece is transferred from the vacuum furnace to the transportable oven under an inert atmosphere to prevent the workpiece from being exposed to an oxidizing atmosphere or from undergoing a phase transition. The transportable oven is adapted to be detached from the vacuum furnace and transported to a work station for further processing of the workpiece. Heating means is provided in the transportable oven to maintain the temperature of the workpiece above a preselected warming temperature while the workpiece is waiting to be processed.
