Abstract

Progress in understanding of properties of materials at high pressure in many respects is connected to diamond anvils technique. We developed and investigated a technique of megabar range pressure valuation, applicable in the opaque high pressure diamond anvil cell (DAC) with anvils of the rounded cone-plane type made of synthetic carbonado-type diamond, consisting of dielectric grains of synthetic diamonds in layers of conducting materials. These anvils are good conductors, permitting measurement of the electrical properties of samples placed between the anvils in DAC by using the anvils as the electrical contacts to the sample.
The purpose of our researches is to reveal the features of phase transformations in Ti - alloy under high pressure.
We report the results of an investigation of the TEMF of Ti - alloys at pressures 15 -50 GPa and room temperature in DAC. It was shown that reversible changes of TEMF take place at pressure increasing and decreasing.
