After ball-milling, TiFe under a pure argon atmosphere, with a small amount of pure nickel, can readily absorb large amounts of hydrogen without any activation process. The H/M system reaches equilibrium after 8 h under 10 bars of hydrogen pressure (H/M = 0.62). Even after 10 days exposure to the air. the same sample reacts with hydrogen, but with slower kinetics. The impact of the ball-milling time on the hydrogen absorption kinetics and the maximum hydrogen content is discussed.
