Nonetheless, the second aspect, i.e., the mechanical behavior of high-entropy alloys, is still largely afloat in abundant literature in a spite of some recent reviews on certain specialized topics [4-6]. In consideration of this insufficiency, the present review intends to offer a comprehensive...

In this work, equiatomic CoCrFeNi high-entropy alloy (HEA) was fabricated by solid-state cold spray additive manufacturing technology and then post-spray annealed at the temperature range of 500–1000 °C for 2 h. By adjusting the annealing temperature, four types of deposits (i.e., as-spr...
precipitation on strain-rate dependent mechanical behavior in a eutectic high entropy alloyMetals and alloysMechanical propertiesRecent studies indicate that eutectic high-entropy alloys can simultaneously possess high strength and high ductility, which have potential industrial applications. The present study ...
In this work, the mechanical characteristics of high-entropy alloy Co20Cr26Fe20Mn20Ni14 with low-stacking fault energy processed by cryogenic and room temperature high-pressure torsion (HPT) were studied. X-ray diffraction, scanning electron microscopy (
The strengthening mechanisms of high-entropy alloys (HEA) include lattice friction, solid solution strengthening, grain refinement, in situ phase transformation, and nanoscale precipitation. Additionally, the grain boundary types play a crucial role in d
Molecular dynamics simulations were employed to investigate the plastic deformation of AlCoCrCu0.5FeNi high-entropy alloy (HEA) nanopillars with a body-centered cubic structure. The plastic deformation of HEA and pure Fe nanopillars was observed to be dominated by deformation twinning . However, the ...
This paper discusses the mechanical behavior and microstructure of Al 0.1 CoCrFeNi HEA subjected to thermo-mechanical processing, and its potential application in peripheral vascular stent implants that are prone to high failure rates. Results show that Al 0.1 CoCrFeNi alloy possesses characteristics ...
It remains a challenge to enhance strength without sacrificing ductility for high entropy alloys. Here, we prepared in-situ TiC/FeCrNiCuV0.1 high entropy alloy matrix composites using vacuum induction smelting. The new composites exhibit an excellent combination of high tensile strength (1006.5?MPa) ...
Consequently, the microstructural origins of its high strength and ductility remain unclear. Even basic features of its plastic deformation behavior including slip planes, Burgers vectors, and dislocation dissociations, have not been reported. In addition, its stacking fault energy has not been ...
