Abstract

Synthesized from ultrafine particles with a bottom-up approach, nanoglasses are of particular importance in pursuing unique properties. Here, we design a metallic nanoglass alloy from two components of ∼Cu64Sc36 and ∼Fe90Sc10 nanoglasses. With nanoalloying mutually immiscible Fe and Cu, the properties of the nanoglass alloys can be tuned by varying the proportions of the ∼Fe90Sc10 component. This offers opportunity to create novel metallic glass nanocomposites and sheds light on building a structure-property correlation for the nanoglass alloys.

摘要

通过自下而上的方法由超细颗粒合成，纳米玻璃在追求独特性能方面具有特别重要的意义。在此，我们从约Cu64Sc36和约Fe90Sc10纳米玻璃的两种组分设计出一种金属纳米玻璃合金。通过对互不相溶的铁和铜进行纳米合金化，纳米玻璃合金的性能可以通过改变约Fe90Sc10组分的比例来调节。这为创造新型金属玻璃纳米复合材料提供了机会，并为建立纳米玻璃合金的结构-性能相关性提供了启示。
