High-entropy alloys (HEAs) have attracted great attention because they provide diversified
possibilities for obtaining many exceptional properties. They are expected to serve as …

In the past decade, multi-principal element high-entropy alloys (referred to as high-entropy
alloys, HEAs) are an emerging alloy material, which has been developed rapidly and has …

The face-centered cubic medium-entropy alloy NiCoCr has received considerable attention
for its good mechanical properties, uncertain stacking fault energy, etc, some of which have …

The present work demonstrates that nitrogen doping inhibits the formation of deformation
twins in a CrMnFeCoNi high entropy alloy, while significantly increases the strength without …

The strength-ductility trade-off has been the long-standing barrier in the pursuit of high-
performance structural materials. Here, by exploiting the merit of interstitial nitrogen, a novel …

We show that interstitial nitrogen doping improves the tensile properties of a CoCrNi alloy. A
material with 0.5 at% interstitial nitrogen was compared to a nitrogen-free CoCrNi alloy. The …

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 …

The microstructures, mechanical properties, and deformation substructures of gradient Mo
0.3 NiCoCr medium-entropy alloys (MEAs) with very coarse grain size created by pre-torsion …

The CrCoNi medium-entropy alloy is not fully utilized at room temperature circumstance due
to its low strength, despite excellent cryogenic mechanical properties. Here we report that, a …

In conventional metallic materials, strength and ductility are mutually exclusive, referred to
as strength-ductility trade-off. Here, we demonstrate an approach to improve the strength …
