摘要：
Zr41.2Ti13.8Ni10Cu12.5Be22.5 bulk amorphous alloy was prepared by arc melting and rapidly casting into a copper mould. Hydrogen charging was performed electrochemically in glycerine-phosphoric acid electrolyte. The effects of hydrogen on the resistivity and the electron binding energy were studied. The results show that hydrogen can increase the electron binding energy of the atom in the bulk amorphous alloy. The change of resistivity is not obvious when the ratio of hydrogen to metal (chi(H)) is 0.29. The resistivity will decrease obviously when the ratios of hydrogen to metal are 0.62 and 0.92. In addition, hydrogen charging makes the jumped temperature of resistivity very low.
