Abstract
While a workpiece is heated and pressed by one of a pair of high-pressure vessels, a workpiece being pressed by the other high-pressure vessel is placed in a heated state. In the reducing process after termination of heating and pressing treatment of the workpiece by one high-pressure vessel, both the high-pressure vessels are placed in communication, and the pressure medium gas released from one high-pressure vessel is poured into the other high-pressure vessel. After pressures of both the high-pressure vessels have assumed a nearly balanced state, the pressure medium gas is sucked out of one high-pressure vessel by a compressor and pressed, and is poured into the other high-pressure vessel, and the workpiece is heated and pressed by the other high-pressure vessel. By the method as described, considerable shortening of cycle time of HIP treatment is achieved, and the HIP treatment can be carried out with high efficiency.
