摘　　要：利用超高真空镀膜法制备了Zr-Nb-Cu合金系统五个不同成分点多层膜样品,成分点分别为Zr63Nb19Cu18、Zr42Nb19Cu39、Zr41Nb39Cu20、Zr19Nb18Cu63和Zr14Nb70Cu16。对样品进行离子束混合实验及相关表征后发现,Zr-Nb-Cu合金系统能形成非晶态合金,但是Nb元素的加入并不利于非晶形成。Zr19Nb18Cu63和Zr41Nb39Cu20多层膜样品得到了非晶态和固溶体的双相结构,此类双相结构比单一非晶相结构具有更好的力学性能。Five sets ofZr-Nb-Cu multilayered films were prepared by the overall composition of Zr63Nb19Cu18, Zr42Nb19- Cu39, Zr41Nb39Cu20, ZrlgNblsCu63 and Zr14Nb70Cu16, respectively, and ion beam mixing experiment was conducted by 200 keV xenon ions. The results show that the Zr-Nb-Cu system is a metallic glass forming one ,but the element Nb is not conducive to the formation of amorphous phase. Under the composition of Zr19Nb18Cu63 and Zr41Nb39Cu20, ion beam mixing results in forming the amorphous-crystalline composite, which may perform better mechanical properties than single-phase glassy alloys.
