中文摘要：

弧融化在这研究被利用生产 Zr ₅₅ Cu ₃₀ Ni ₅ 在有到氩的高纯净的氢的各种各样的比率的混合气氛下面的艾尔 ₁₀ 合金。团结结构和 Zr ₅₅ Cu ₃₀ Ni ₅ 艾尔 ₁₀ 合金被在演员组铸块锭的不同部分检验微观结构决定。结果证明结晶化结构的不同的度在 ascast 被获得在弧融化在高纯净的 Ar 以后的钮扣铸块锭，和 arcmelted 铸块锭的代表性的团结形态学被发现与从底部变化起来由晶体组成。由对比，在铸块锭由把 10% H ₂ 加到高纯净的 Ar 空气制作了的当演员组钮扣的中间、上面的区域有完全非结晶的结构。一个清楚的团结接口在 ascast 在水晶和玻璃之间被发现扣好铸块锭，它显示氢增加能提高 Zr ₅₅ Cu ₃₀ Ni ₅ 艾尔 ₁₀ 合金形成眼镜的能力。为这负责的精确机制也被调查。

英文摘要：

Arc melting was utilized in this study to produce Zr_（55）Cu_（30）Ni_5Al_（10） alloys under mixed atmospheres with various ratios of high-purity hydrogen to argon. The influences of hydrogen addition on the solidification structure and glass-forming ability of Zr_（55）Cu_（30）Ni_5Al_（10） alloy were determined by examining microstructures in different parts of the cast ingots. The results showed that different degrees of crystallization structures were obtained in the ascast button ingots after arc melting in high-purity Ar, and the cross-sectional solidification morphology of arcmelted ingots was found to consist of crystals with varying from the bottom up. By contrast, there were completely amorphous structures in the middle and upper areas of the as-cast button ingots fabricated by adding 10% H_2 to the high-purity Ar atmosphere. A clear solidification interface was found between the crystal and glass in the ascast button ingots, which indicates that hydrogen addition can enhance the Zr_（55）Cu_（30）Ni_5Al_（10） alloy＇s glass-forming ability. The precise mechanism responsible for this was also investigated.
