Comment on: High Mixing Entropy Enhanced Energy States in Metallic Glasses

TL;DR

This paper comments on a study that investigated how mixing entropy influences energy states and stability in metallic glasses, emphasizing the need to consider compositional effects.

Contribution

It highlights the importance of considering compositional contributions in analyzing the effects of mixing entropy on metallic glasses.

Findings

Mixing entropy correlates with energy states and stability in metallic glasses.

The original study may have overlooked compositional effects.

Further analysis is needed to isolate entropy effects from composition.

Abstract

A recent paper by Juntao Huo et al [Chin. Phys. Lett. 39 (2022) 0464011] reported a correlation between the entropy of mixing (and the corresponding energy state) and the thermal stability and mechanical parameters, for three Zr-Ti-Cu-Ni-Be metallic glasses (MG) including a high-entropy one (HEMG). The authors dismissed a possible compositional contribution to the variations of the thermal stability and mechanical parameters studied.
