摘　　要：研究两种不同成分具有较大过冷液相区的四元合金Zr65Al7 5Ni1 0 Cu1 7 5和Zr65Al1 0 Ni1 0 Cu1 5非晶和晶态薄带吸氢行为,结果表明两种薄带的吸氢量均随着温度的升高而增大,非晶薄带的吸氢量要小于同等条件下的晶态薄带的吸氢量且只有在673K吸氢后形成了氢化物,Zr65Al7 5Ni1 0 Cu1 7 5非晶和晶态薄带吸氢后分别生成了Zr2 NiH4 7和ZrH2 ;而Zr65Al1 0 Ni1 0Cu1 5非晶和晶态两种薄带最后生成的氢化物同为ZrH2 。The hydrogen absorption behavior of the amorphous and crystalline ribbons of Zr_ 65Al_ 7.5Ni_ 10Cu_ 17.5 and Zr_ 65Al_ 10Ni_ 10Cu_ 15 alloys with the bigger overcooling liquid phase region was studied.It was observed that the hydrogen absorption capacity of both ribbons increased with the temperature rising,the hydrogen absorption capacity of the amorphous ribbons was less than that of the crystalline ones at the same condition,the hydride was generated in the amorphous ribbons at 673 K.The hydride generated in the amorphous and crystalline ribbons of Zr_ 65Al_ 7.5Ni_ 10Cu_ 17.5 alloy after absorbing hydrogen were Zr_2NiH_ 4.7 and ZrH_2 respectively.The hydride generated in the amorphous and crystalline ribbons of Zr_ 65Al_ 10Ni_ 10Cu_ 15 alloy after absorbing hydrogen was the same ZrH_2.
