Reactivemechanicalgrinding (MG under H2) was applied to a (Ti+Ni) mixture. After only 1 h, all the titanium is transformed into TiH2. After 10 h of milling the TiH2 is nano-structured and it takes approximately 25 h to obtain nano-structured Ni. After 45 h no binary compound is formed between Ti (or TiH2) and Ni and a very homogeneous nano-structured mixture is formed. The electrochemical capacity is approximately 150 mAh g−1 and almost constant upon cycling. Finally the RMG process of TiNi mixture allows one to obtain a partial conversion of ingot into powder.< Leer menos
