Measurements of hydrogenated titanium by electric methods

The titanium alloy (VT1-0) was investigated during the hydrogenation in gaseous atmosphere at the temperatures of 600 °C using the Sieverts method. The samples were analyzed with the eddy and direct currents. The dislocation density (Nd) was calculated as a function of the weight concentration of hydrogen in titanium according to X-ray spectra. The X-ray line broadening method was used. The value Nd was associated with the electrical resistivity ρd of hydrogenated titanium. The phase composition was analyzed using the database (PCPDFWIN and PDF-4+) and the full-profile analysis programs (POWDER CELL 2.5). The change in the hydrogenation of titanium leads to a change in the concentration of defects and the behavior of eddy currents depending on the frequency. This indicates a change in the hydrogen concentration through the thickness of the sample. The concentration of hydrogen was changed in depth using a spectrum magnetic analyzer (SMA II, Germany). The direct current resistivity of the titanium samples ...
