“…barriers for vacancy migration were attributed to the mixing enthalpies arising from the combination of multiple principal elements, which were implicitly influenced by lattice distortion. Zhao et al [137] conducted a more detailed study and found that the BCC VTaCrW HEA had a wider range of vacancy formation energies than FCC HEAs due to its larger atomic volume misfit. The formation energy of vacancies that substitute V and Cr decreased in the distorted lattice compared with that in pure metals, while there were higher fluctuations in the formation energy of vacancies that substitute Ta and W. These results revealed a complex diffusion behavior of atoms in a severely distorted lattice.…”

“…However, other studies have shown that lattice distortion can accelerate constituent diffusion in different HEAs. For instance, the mean migration energy of Ta in BCC VTaCrW was even lower than in pure Ta; [ 137 ] and faster diffusion of Zr was observed in BCC TiZrHfNbTa and TiZrHfNbV HEAs compared to the geometric mean of their constituents. This phenomenon was attributed to a lattice mismatch δ greater than 3%.…”

Since 2004, the design of high entropy alloys (HEAs) has generated significant interest within the materials science community due to their exceptional structural and functional properties. By incorporating multiple principal elements into a common lattice, it is possible to create a single‐phase crystal with a highly distorted lattice. This unique feature enables HEAs to offer a promising combination of mechanical and physical properties that are not typically observed in conventional alloys. In this article, we provide an extensive overview of multifunctional HEAs that exhibit severe lattice distortion, covering the theoretical models that were developed to understand lattice distortion, the experimental and computational methods employed to characterize lattice distortion, and most importantly, the impact of severe lattice distortion on the mechanical, physical and electrochemical properties of HEAs. Through this review, we hope to stimulate further research into the study of distorted lattices in crystalline solids.This article is protected by copyright. All rights reserved
