Abstract: Studied VT1-0 titanium alloy under the conditions of the hydrogenation gas environment attemperatures up to 600◦C. Analysis of samples by eddy (by dielectric loss) and constant current. According to Xray,researchers calculated the dislocation density Nd as a function of the weight concentration of hydrogen intitanium. The value compared with the electrical resistance ρd of the hydrogenated titanium. Changing of thehydrogenated titanium leads to the changes of the character of the eddy currents, depending on their frequency,which indicates a change in hydrogen concentration over the sample thickness. These data may be useful inspecific applications, application of the combined methods of electro analysis of hydrogen in metals.Hydrogenation was carried out by Sieverts method. The formation of titanium with defects leads to ambiguouschange in electric conductivity that caused by uneven distribution of defects in metal and a change of the abilityaccumulate hydrogen sample volume. Interconnection between the degree of hydrogenation of a titanium alloyand a change in the electric conductivity by the combined use of constant and eddy current makes the possible tothe quantitative measurement of the number of defects created hydrogen in titanium, which is useful in practical terms.
