We develop a technique for measuring the coefficient of hydrogen diffusion in metals of group V based on an electricaly conductivity method. By using this technique, we measured the coefficient of hydrogen diffusion in vanadium and niobium in the temperature range 573 – 1373 K and calculated the hydrogen permeability of metals of group V. A high-temperature phase transition caused by hydrogen dissolution was discovered in this work for the first time.
