Published in 2020 at "Acta Materialia"

DOI: 10.1016/j.actamat.2020.05.003

Abstract: Abstract The possibility of designing multi-principal element alloys in the Ni-Co-Ru system is investigated by first-principles and experimental means. A high-throughput first-principles approach is employed to probe the effect of composition on planar fault energies.… read more here.

Published in 2020 at "Acta Materialia"

DOI: 10.1016/j.actamat.2020.06.022

Abstract: Abstract Many of the purported virtues of Multi-Principal Element Alloys (MPEAs), such as corrosion, high-temperature oxidation and irradiation resistance, are highly sensitive to vacancy diffusivity. Similarly, solute interdiffusion is governed by vacancy diffusion. It is… read more here.

Published in 2020 at "Journal of Alloys and Compounds"

DOI: 10.1016/j.jallcom.2020.154025

Abstract: Abstract A direct laser deposition processing method was applied to construct compositional and microstructural libraries of AlxCoCrFeNi in an efficient and high-throughput manner. Among the compositions (x = 0.51–1.25) and quench rates (26–6400 K/s) studied, most of the… read more here.

Published in 2019 at "Materials today communications"

DOI: 10.1016/j.mtcomm.2019.100658

Abstract: Abstract We report on the influence of Mn additions on the microstructure and properties of (CoCrCuTi)100−xMnx multiprincipal element alloys (MPEAs) containing 5, 10, 15, and 20% Mn prepared by arc-melting. It was observed that the… read more here.

Published in 2021 at "Thin Solid Films"

DOI: 10.1016/j.tsf.2021.138721

Abstract: Abstract Nitrides based on multi-principal element alloys have been deposited by reactive magnetron sputtering from powder targets. All deposited nitrides were based on alloys of which the majority of the constituent metals have a low… read more here.

Published in 2022 at "Science Advances"

DOI: 10.1126/sciadv.abq7433

Abstract: Multi–principal element alloys (MPEAs) containing three or more components in high concentrations render a tunable chemical short-range order (SRO). Leveraging large-scale atomistic simulations, we probe the limit of Hall-Petch strengthening and deformation mechanisms in a… read more here.
