N2 - The paper studies electrochemical hydrogenation of Ti-Ni powder after mechanical activation. High-energy mechanical activation was performed using a planetary ball mill with rotation speed of 1820 rpm for 10 s. The initial powder after mechanical activation has a mixture of phases TiNi (B2) and (B19c), Ti2Ni, and TiNi3 with the lattice parameters corresponding to those reported in literature. When hydrogenation time increases, the lattice parameter of the Ti2Ni phase only significantly changes, and 90 min of hydrogenation is the incubation period of this process, when the lattice parameter of the Ti2Ni phase changes within the error. Electrochemical hydrogenation performed for more than 90 minutes causes formation of the Ti2NiHx phase based on Ti2Ni, and 140 and 180 min of hydrogenation is sufficient to form the Ti2NiH0.5 stoichiometry.
