This paper reviews the recent research and development of high-entropy alloys (HEAs).
HEAs are loosely defined as solid solution alloys that contain more than five principal …

Abstract High-entropy alloys (HEAs), as a new class of materials, are nearly equiatomic and
multi-element systems, which can crystallize as a single phase or multi-phases. Most of the …

The present work investigates the influence of Al-content and potential-scan-rate on
stable/metastable pitting of Al x CoCrFeNi high-entropy alloys in a 3.5 wt.% NaCl solution …

Serration and noise behaviors in plastically deforming solids are related to avalanches of
deformation processes. In the stress-strain curves, the serration characteristics are visible as …

Power laws and distributions with heavy tails are common features of many complex
systems. Examples are the distribution of earthquake magnitudes, solar flare intensities and …

In the past twenty years, new experimental approaches, improved models and progress in
simulation techniques have brought new insights into longstanding issues concerning …

Prior to macroscopic yielding, most materials undergo a regime of plastic activity that cannot
be resolved in conventional bulk deformation experiments. In this pre-yield, or micro-plastic …

High-entropy alloys (HEAs) are a novel class of alloys that have many desirable properties.
The serrated flow that occurs in high-entropy alloys during mechanical deformation is an …

Recent experimental and theoretical progress on the study of crackling noise in the plastic
deformation of crystals, ferroelastics, and porous materials is reviewed. We specifically point …

The physical processes governing the onset of yield, where a material changes its shape
permanently under external deformation, are not yet understood for amorphous solids that …
