Abstract

Requirements for the mechanical properties of compressible gaskets are studied to realize the ideal mode of pressure generation in the MA8 apparatus. With single-component gaskets it is difficult to generate very high pressures; the use of composite metal gaskets is proposed to satisfy all the requirements for optimum pressure generation. The newly devised composite metal gaskets are examined experimentally for generation of pressures up to 15-18 GPa in 0. 05 cm**3. Theoretical analysis of the experimental results calculates the distribution of stress in the anvils from the strength data of the metals used for the gaskets, and also the distribution of plastic strain from data on plastic deformation of the anvils. Combining the calculated stress and the plastic strain in the anvils, we have derived a safety limit of approx 4. 5 GPa for the differential stress in cemented tungsten carbide anvils used in the present work.
