High-entropy alloys are an intriguing new class of metallic materials that derive their
properties from being multi-element systems that can crystallize as a single phase, despite …

Technologically important mechanical properties of engineering materials often degrade at
low temperatures. One class of materials that defy this trend are CrCoNi-based medium-and …

Equiatomic multi-component alloys, referred to variously as high-entropy alloys, multi-
component alloys, or compositionally complex alloys in the literature, have recently received …

High-entropy alloys are equiatomic, multi-element systems that can crystallize as a single
phase, despite containing multiple elements with different crystal structures. A rationale for …

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) …

CrCoNi-based high-entropy alloys have demonstrated outstanding mechanical properties,
particularly at cryogenic temperatures. Here we investigate the fatigue-crack propagation …

We systematically compared the mechanical properties of CrCoNi, a recently emerged
prototypical medium-entropy alloy (MEA) with face-centered-cubic (FCC) structure, with …

Near-equiatomic multi-component high-entropy alloys (HEAs) have engendered much
attention of late due to the remarkable mechanical properties of some of these new metallic …

Damage tolerance can be an elusive characteristic of structural materials requiring both high
strength and ductility, properties that are often mutually exclusive. High-entropy alloys are of …

A new class of materials called high-entropy alloys (HEAs) constitutes multiple principal
elements in similar compositional fractions. The equiatomic Fe 20 Mn 20 Cr 20 Co 20 Ni 20 …
