Through controlled mechanical alloying treatment, TiFe and LaNi5 particles combined together on the surface of TiFe. This kind of compound particles can be easily activated at room temperature and an H2-pressure of 4.0 MPa. LaNi5 particles provided “window” and “path” for entrance of hydrogen from the surface to the interior of TiFe alloy.
