摘要
利用电弧熔炼及铜模快速铸造的方法,制备Zr41.2Ti13.8Cu12.5Ni10Be22.5块体非晶合金,通过电化学方法向块体非晶中充入氢。研究了氢对块体非晶合金电子结合能和电阻率的影响。结果表明:氢能够提高非晶合金原子的电子结合能;当氢容量等于29%(摩尔分数,下同)时,电阻率无明显的变化;氢容量等于62%和92%时,电阻率随着氢容量的增加显著降低;并且,充氢使电阻率突变温度降低。
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 （ZH） 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.
