Finite element analysis of the high-pressure tungsten carbide radius-anvil

Abstract

The high-pressure tungsten carbide (WC) radius-anvil is analyzed and studied based on the finite element method (FEM). The results indicat that under the same transfer efficiency of pressure, the lifetime of high-pressure WC radius-anvil is longer than that of the traditional anvil, which can be enhanced about 3.05%16.75%. The highest sample cell pressure generation by the new design of high-pressure WC radius-anvil increases about 5% (from 5.80 GPa to 6.09 GPa) compared with that by the traditional anvil, which can be attributed to the technology of radius-bevel. The high-pressure WC radius-anvil will be indeed very useful to broaden the synthetic region of functional materials. Further more, in this work, the operational costs of cubic high-pressure apparatus is reduced and the cubic anvil type high pressure techniques is improved in many important aspects.
