采用铜模喷铸成形法制备Cu50Zr50、Cu62-xZr38-xAl2x(2x=2at％、4at％和6at％)和Cu46Zr47-xAl7Yx(x=4at％ ～7at％)大块非晶试样.通过X射线衍射分析、扫描电子显微镜和示差扫描量热计(DSC)分别研究添加元素Al与Y对Cu-Zr二元合金非晶形成能力、显微形貌和热稳定性的影响.结果表明:所制备的Cu50Zr50、Cu61Zr37Al2为非晶合金,基体中含极少量结晶相,非晶形成能力对Cu-Zr-Al成分较为敏感；Y含量对直径为4 mm的Zr47-xCu46Al7Yx非晶形成能力和显微组织有着显著影响,Y含量4at％时,基体中含极少量结晶相,Y含量5at％ ～ 7at％时,非晶合金呈现完全无特征组织.
