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.

Influence of NbC particles on microstructure and mechanical properties of AlCoCrFeNi high-entropy alloy coatings prepared by laser cladding
Xiaofeng Li,Xiaofeng Li,Yinghao Feng,Bin Liu,Denghao Yi,Xiaohui Yang,Weidong Zhang,Gang Chen,Yong Liu,Peikang Bai +9 more
TL;DR: In this paper, AlCoCrFeNi-xNbC high-entropy alloy (HEA) coatings were prepared by laser cladding and the phase constituents, microstructure and mechanical properties of the HEAs were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), electron back-scatter diffraction, transmission electron microscope (TEM), microhardness and wear resistance tests.

Twinning in metastable high-entropy alloys.
Shuo Huang,He Huang,Wei Li,Wei Li,Dongyoo Kim,Dongyoo Kim,Song Lu,Xiaoqing Li,Erik Holmström,Se Kyun Kwon,Levente Vitos,Levente Vitos +11 more
TL;DR: The authors show that twinning can be a primary deformation mechanism in three well-known medium- and high-entropy alloys that have unstable face-centered cubic lattices.

A simple analytic theory for the statistics of avalanches in sheared granular materials
TL;DR: In this paper, an analytic model for the effect of void fractions within a granular medium on avalanche statistics is proposed. But the model is inherently discrete and it is not applicable to the case of high packing fractions.

Emergence of Scaling in Random Networks
TL;DR: A model based on these two ingredients reproduces the observed stationary scale-free distributions, which indicates that the development of large networks is governed by robust self-organizing phenomena that go beyond the particulars of the individual systems.

Nanostructured High-Entropy Alloys with Multiple Principal Elements: Novel Alloy Design Concepts and Outcomes
Jien-Wei Yeh,Swe-Kai Chen,Su-Jien Lin,Jon-Yiew Gan,Tsung-Shune Chin,Tsung-Shune Chin,Tao-Tsung Shun,Chun-Huei Tsau,Shou-Yi Chang +8 more
TL;DR: A new approach for the design of alloys is presented in this paper, where high-entropy alloys with multi-principal elements were synthesized using well-developed processing technologies.
Journal ArticleDOI
Self-organized criticality: An explanation of the 1/ f noise
TL;DR: It is shown that dynamical systems with spatial degrees of freedom naturally evolve into a self-organized critical point, and flicker noise, or 1/f noise, can be identified with the dynamics of the critical state.

Microstructural development in equiatomic multicomponent alloys
Brian Cantor,Brian Cantor,I.T.H. Chang,I.T.H. Chang,P. Knight,P. Knight,A.J.B. Vincent,A.J.B. Vincent +7 more
TL;DR: In this paper, it was shown that the confusion principle does not apply, and other factors are more important in promoting glass formation of late transition metal rich multicomponent alloys.
