Review of Powder Bed Fusion Additive Manufacturing for Metals (2021, background): “Grain refinement and grain boundary strengthening was the dominating mechanism for higher strength of laser-melted CoCrFeMnNi HEAs due to Hall–Petch relationship [358,376].”
Effect of second phase particles on mechanical properties and grain growth in a CoCrFeMnNi high entropy alloy (2019, background): “6) can therefore be mainly attributed to the fine-grained fully recrystallized fcc matrix [47].”
Influence of deformation and annealing twinning on the microstructure and texture evolution of face-centered cubic high-entropy alloys (2017, neutral): “Besides the high-entropy effect that stabilizes the solid solution, also inherently slow diffusion kinetics, a severe lattice distortion, and the so-called ‘cocktail effect’ influence the properties of HEAs [5, 7-9], although the influence of these effects are discussed critically in open literature”
