Abstract：

The invention discloses a modifying method of AB2-typed hydrogen-reserving property of hydrogen-reserving alloy in the alloy making technical domain, which is characterized by the following: designing each component of AB2-typed hydrogen-reserving alloy with purity over 99.9%; adding Nb element to allocate into new alloy; adopting non-consumable (tungsten electrode) vacuum arc furnace to fuse alloy; guaranteeing the casting component and tissue uniformity; inhibiting gravity segregation; adopting Zr and Ti as atom A and Cu, Fe, Ni, Mn, Cr, Co, V, Pd and Nd as atom B; adding Nb element to change microscopic structure and tissue shape of hydrogen-reserving alloy; improving the stability of hydrogen-reserving property effectively.
