  • Effect of nickel alloying by using ball milling on the hydrogen .

    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 HM system reaches equilibrium after 8 h under 10 bars of hydrogen pressure (HM = 0.62). Even after 10 days exposure to the air, the same sample.
