摘要：
A method for improved HIPing of filament reinforced metal matrix composite samples is disclosed. The method departs from conventional HIPing practice in that it does not rely on the heating of the HIPing gas in order to increase pressure. Rather, the temperature of the article and of the HIPing gas is first to the HIPing temperature and the pressure of the gas and the pressure on the sample is then raised to the HIPing pressure. Benefits are derived in that a lower level of filament fracture results.
