Abstract
A method and apparatus is provided for rapidly 'pressure quenching' or reducing the pressure on samples from very high pressures at rates substantially in excess of 10.sup.6 up to 10.sup.10 bars, or atmospheres, per second, or more, while avoiding damage to the high pressure system. The high pressure system is comparable to that employed to make artificial diamonds, and includes optional arrangements for heating, cooling, and applying electric and magnetic fields to the pressure quenched sample. Special arrangements are provided for circulating cooling fluid in the vicinity of the metastable material to rapidly cool it, immediately prior to decompression.
