On Lattice Distortion in High Entropy Alloys (2018, methodology): “At the first attempt, X-Ray diffraction was used as the means of characterization (Yeh et al., 2007; Tsai and Yeh, 2014; Yeh, 2015) with the basic assumption that large lattice distortion would reduce the intensity of diffraction peaks.”
Understanding the physical metallurgy of the CoCrFeMnNi high-entropy alloy: an atomistic simulation study (2018, methodology): “Before starting the computation of any specific materials properties, we examined whether the present interatomic potential yields a stable fcc random solid solution for the equiatomic CoCrFeMnNi HEA (designated CoCrFeMnNi HEA hearafter) in the typical process temperature range (1073–1473 K), as has”

High-entropy alloys: a critical assessment of their founding principles and future prospects (2016, methodology): “dislocations are not consistent with the localised strain proposed by Yeh et al.(3,8,65,75,97,180) Toda-Caraballo and Rivera-Diáz-del-Castillo(185) have recently predicted lattice strains in HEAs using both a density function theory (DFT) approach, and a spring model based on quadratic potentials.”
Review of Recent Research on AlCoCrFeNi High-Entropy Alloy (2021, background): “Due to their occurrence in high-entropy alloys, the principles of physical metallurgy are different from those in classical alloys, affecting the mechanical, physical and chemical properties, thermodynamics, structure, and microstructure of the alloy [31].”
Thermodynamic instability of a nanocrystalline, single-phase TiZrNbHfTa alloy and its impact on the mechanical properties (2018, background): “Firstly, there is a severe lattice distortion [11,12], which should lead to an inherently high strength due to strong solid solution hardening, especially in bcc HEAs [13].”
Clarifying the four core effects of high-entropy materials (2024, unknown): “Yeh proposed a set of four core effects for HEAs 1,35,55–57 — high-entropy, severe-lattice-distortion, sluggish-diffusion and cocktail effects — which corresponds to the four aspects of materials — thermodynamics, structure, kinetics and performance.”
