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 …

CrCoNi-based medium-and high-entropy alloys display outstanding damage tolerance,
especially at cryogenic temperatures. In this study, we examined the fracture toughness …

Multiple-basis-element (MBE) alloy was defined as the entropy of mixing over 1R (R is the
gas constant, 8.31 J/k), and contains at least three principal elements, each one at over 5 …

Seldom could metals and alloys maintain excellent properties in cryogenic condition, such
as the ductility, owing to the restrained dislocation motion. However, a face-centered-cubic …

While the impact of grain boundary strengthening on dislocation slip is particularly effective
in the equiatomic CrMnFeCoNi high-entropy alloy (HEA), its effect on deformation twinning …

We report on the low-cycle fatigue behavior of single-phase, face-centered cubic CoCrNi
and CoCrFeMnNi at room temperature. Both alloys manifest cyclic hardening followed by …

In this study, the CoCrNi medium entropy alloy (MEA) was successfully fabricated by laser
aided additive manufacturing (LAAM), a directed energy deposition (DED) process. Results …

We studied the deformation behavior of CrFeCoNi high-entropy alloy by in situ neutron
diffraction at room temperature, intermediate low temperature of 140 K, low temperatures of …

Plastic deformation during low-cycle fatigue (LCF) in equiatomic face-centered cubic (FCC)
CoCrFeMnNi high-entropy alloys (HEAs) is accumulated by dislocation substructure …

Phase transformation is an effective means to increase the ductility of a material. However,
even for a commonly observed face-centered-cubic to hexagonal-close-packed (fcc-to-hcp) …
