From High‐Entropy Alloys to High‐Entropy Steels

steel research international, 2015
Inspired by high‐entropy alloys, we study the design of steels that are based on high configurational entropy for stabilizing a single‐phase solid solution matrix. The focus is placed on the system Fe–Mn–Al–Si–C but we also present trends in the alloy system Fe–Mn–Al–C.

Hydrogen solution in high-entropy alloys

Physical Chemistry Chemical Physics, 2021
Using DFT calculations we revealed the origins of the variation of the H solution energy induced in high-entropy alloys (HEAs), and then proposed a predictive model that is universal and available for assessing the distributions of H solution energies in HEAs.

Phase stabilities of high entropy alloys

Scripta Materialia, 2019
Abstract A perturbation model is used to evaluate the phase stabilities of high entropy alloys. The calculation results can successfully predict the phase stabilities of many high entropy alloys and shows that stable single phase high entropy alloys are rare.

Discovery of a Superconducting High-Entropy Alloy

Physical Review Letters, 2014
High-entropy alloys (HEAs) are multicomponent mixtures of elements in similar concentrations, where the high entropy of mixing can stabilize disordered solid-solution phases with simple structures like a body-centered cubic or a face-centered cubic, in competition with ordered crystalline intermetallic phases.
