Abstract
We undertook an investigation of the influence of thermobaric treatment on the electron-energy spectrum of the oxycarbide VC/sub 0.44/O/sub 0.48/ and the oxynitride VN/sub 0.46/ /times/ O/sub 0.50/ of vanadium. For this purpose we obtained the V K/sub /beta/5/ x-ray emission spectra of the compounds in their original state and after thorough compression. The thermobaric treatment of these compounds were carried out by holding the original samples for 1-2 min under pressures of 7.7 and 9.0 GPa at temperatures of 1800 and 1600/degree/C, respectively. This treatment resulted in an increase in the lattice constant from 4.1360 to 4.1647 /angstrom/ in the case of the oxycarbide and from 4.1161 to 4.1370 /angstrom/ in the case of the oxynitride with a corresponding increase in density. The calculations of the number of particles in the unit cell showed that the filling of structural vacancies in the unit cell takes place in both compounds. The study of the V K /sub /beta/5/ x-ray emission spectra was carried out on a FRS-KD-1 x-ray fluorescence spectrometer.
