研究了Ar离子辐照Zr-Al-Cu-Ni非晶合金的显微结构演变。在离子辐照下，形成了由晶态和非晶态结构组成的Cu和Ni富集纳米结构（直径为30-50 nm）。此外，还观察到直径为5-20 nm的Cu和Ni耗尽的纳米结构。这些纳米结构的形成可以归因于Cu和Ni原子在辐照的金属玻璃中的迁移。
The microstructural evolution of a Zr-Al-Cu-Ni metallic glass induced by irradiation with Ar ions was investigated. Under ion irradiation, the Cu- and Ni-enriched nanostructures (diameter of 30–50 nm) consisted of crystalline and amorphous structures were formed. Further, Cu- and Ni-depleted nanostructures with diameters of 5–20 nm were also observed. The formation of these nanostructures can be ascribed to the migration of Cu and Ni atoms in the irradiated metallic glass.
