In this work TiNi-based nanocrystalline alloys and composite were produced by mechanical alloying process with subsequent annealing at 750°C for 0.5 h. Mechanical alloying was performed in a SPEX 8000 Mixer Mill. TiNi alloy was chemically modified by Ag elemental powder. Silver content equaled 5 wt%. X-ray diffraction analyses revealed formation of TiNi main phase after annealing. Additionally, two minor phases Ti_2Ni and TiNi_3 were detected for unmodified alloy. Crystallites of obtained powders were nanosized. Corrosion and electrochemical measurements were performed in 6 M KOH solution. All synthesized materials were used as negative electrode for Ni-MH_x batteries. Ag addition positively affects on stability of discharge capacity of TiNi alloy during of charge/discharge tests.
