Abstract
A hot isostatic pressing method is disclosed wherein workpieces are accommodated within a high pressure vessel and the interior of the high pressure vessel is filled with an inert gas of a high temperature and a high pressure to treat the workpieces. The method includes a cooling step which is performed after maintaining the interior of the high pressure vessel at a high temperature and a high pressure for a predetermined time and in which a liquid inert gas is fed into the high pressure vessel. According to this method it is possible to shorten the cycle time of an HIP apparatus.
