High-entropy alloys
TL;DR: This Review discusses model high-entropy alloys with interesting properties, the physical mechanisms responsible for their behaviour and fruitful ways to probe and discover new materials in the vast compositional space that remains to be explored.
Journal ArticleDOI
Mechanical properties of high-entropy alloys with emphasis on face-centered cubic alloys
TL;DR: In this paper, the authors review the principal mechanical properties of multi-principal element alloys with emphasis on the face-centered cubic systems, such as the CrCoNi-based alloys, and suggest their favorable mechanical properties and ease of processing by conventional means suggest extensive utilization in many future structural applications.
Journal ArticleDOI
Understanding the physical metallurgy of the CoCrFeMnNi high-entropy alloy: An atomistic simulation study
TL;DR: In this article, the effect of individual elements on solid solution hardening for the equiatomic CoCrFeMnNi HEA based on atomistic simulations is investigated and a significant number of stable vacant lattice sites with high migration energy barriers exists and is thought to cause the sluggish diffusion.
Journal ArticleDOI
Mechanical behavior of high-entropy alloys
TL;DR: In this article, the authors present a comprehensive, critical review of the mechanical behavior of high-entropy alloys and some closely related topics, including thermodynamics and kinetics.

Dynamically reinforced heterogeneous grain structure prolongs ductility in a medium-entropy alloy with gigapascal yield strength
TL;DR: A three-level heterogeneous grain structure with grain sizes spanning the nanometer to micrometer range, imparting a high yield strength well in excess of 1 GPa leads to a sustainable strain hardening rate, a record-wide hysteresis loop in load−unload−reload stress−strain curve and hence high back stresses.

Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.

Special points for brillouin-zone integrations
Hendrik J. Monkhorst,J.D. Pack +1 more
TL;DR: In this article, a method for generating sets of special points in the Brillouin zone which provides an efficient means of integrating periodic functions of the wave vector is given, where the integration can be over the entire zone or over specified portions thereof.
