A nanoglass alloying immiscible Fe and Cu at the nanoscale

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.
