ABSTRACT:
Apparatus and methods are disclosed for the rapid generation of high hydrostatic pressures and the concurrent delivery of said pressures to a workpiece. The apparatus and methods comprise the rapid thermal expansion and vaporization of a volatile fluid. The volatile fluid is typically liquid argon and heated typically by means of a controllable electric heater, delivered to the workpiece typically by means of a pressure-rupturable membrane. The disclosed apparatus and methods permit the application of high hydrostatic pressures to commercial-scale workpieces, in an economic manner and with reduced cycle times.
