    Abstract
  • Travel time in WC anvils was measured using pulse reflect method at room temperature and under cell pressure up to 3.0 GPa. Experimental results indicate that the travel time in the WC anvils decreased linearly with cell pressure. A possible reason for this result is that the anvil was compressed during loading. The relationship between travel time decrease (t/s) and cell pressure (p/GPa) is t=(0.022 330.000 81)p. Compressional wave velocity under high pressure can be corrected using this formula. As an example, compressional wave velocities under high pressure in three rock samples were corrected.
