摘要：

基于有限元法, 对新型圆角式高压碳化钨硬质合金顶锤进行了分析与研究.研究结果表明: 新型圆角式高压碳化钨硬质合金顶锤在不降低顶锤的传压效率的前提下, 能够将顶锤的使用寿命延长3.05%–16.75 %; 新型圆角式高压碳化钨硬质合金顶锤获得的极限腔体压力值可增加至6.09 GPa, 较传统顶锤(5.80 GPa)提高5%, 从而扩宽高压下功能材料的合成区间.新型圆角式高压碳化钨硬质合金顶锤的使用, 将降低六面顶液压机的使用成本, 促进高压技术和材料科学等学科的发展.

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.

Keywords： radius-anvil cubic high pressure apparatus HPHT FEM
