Iron titanium alloy (TiFe) is considered as one of the promising metal hydrides candidates for hydrogen storage. However, the first activation, the so-called activation, of this alloy is a difficult and energy intensive process. Therefore, we have synthesized TiFe alloy doped with 4 wt% Zr and 2 wt% Mn. For practical use, hydrogenation kinetics of the synthesized alloy has been investigated after air exposure. It has been observed that hydrogenation kinetics of the alloy is slower and the incubation time increases. The alloy could not absorb hydrogen after 30 days of air exposure. Thereafter, the alloy was mechanically treated using cold rolling and ball milling processes to restore the hydrogenation kinetics. The air exposed alloy could be successfully hydrogenated after 30 min of ball milling under argon or after cold rolling.
