Abstract

Titanium deuterides TiD x (x = 1.92, 1.98, 2.0) and the Ti0.95Zr0.05D1.76 alloy were studied by 2H NMR in magnetic fields of 4.69 and 7.04 T in the temperature range 120–500 K. The correlation coefficients of deuteron self-diffusion calculated from the temperature dependence of the line width were described by the Arrhenius equation. The activation energies E a and preexponential factors were determined. For the Ti0.95Zr0.05D1.76 alloy, the line width was found to depend on the magnetic field, which was explained by the fact that deuterons are in different environments formed by titanium and zirconium atoms.
