制备了6种合金Zr65.5A15.6Ni6.5Cu22.4,Zr65.3A16.5Ni8.2Cu20,Zr65A17.5Ni10Cu17.5,Zr64.8A18.3Ni11.4Cu15.5,Zr64.5A19.2Ni13.2Cu1.3 1和Zr63.8Al11.4Ni17.2Cu7.6,共晶成分位于合金Zr64.5Al9.2Ni13.2Cu13.1和合金Zr63.8Al11.4Ni17.2Cu7.6的成分之间.这6种合金均显示了非晶相的形成和较宽的过冷液相区范围△Tx值.以及较大的约化玻璃转变温度Trg值.除合金Zr63.8Al11.4Ni17.2Cu7.6的△Tx值为87 K外,其余5种成分合金的△Tx值均在97 K以上.最宽的达105 K,表明这6种合金是一个具有大玻璃形成能力和高热稳定性的非晶合金系列.合金Zr63.8Al11.4Ni17.2Cu7.6是6种合金中玻璃形成能力和热稳定性最高的.其Tg、Tx和Trg值最高Inoue非晶合金Zr65Al7.5Ni10Cu17.5并不是最佳非晶成分.提出以等电子浓度和等原子尺寸规律作为设计大块非晶合金成分的判据
