ABSTRACT:
A method for treating articles with heat and pressure is disclosed. The articles are placed in an isostatic press, the press is evacuated of air and thereafter filled with an inert gas, the pressure and temperature of which is raised to predetermined levels. These predetermined levels are maintained for a period of time sufficient to effect the treatment, and thereafter the inert gas is circulated to promote cooling of the gas and reduce the cooling time of the press and the article treated.
