Alloying has long been used to confer desirable properties to materials. Typically, it involves
the addition of relatively small amounts of secondary elements to a primary element. For the …

Conventional alloys are usually based on a single host metal. Recent high-entropy alloys
(HEAs), in contrast, employ multiple principal elements. The strength of HEAs is …

Realizing improved strength–ductility synergy in eutectic alloys acting as in situ composite
materials remains a challenge in conventional eutectic systems, which is why eutectic high …

Severe lattice distortion is a core effect in the design of multiprincipal element alloys with the
aim to enhance yield strength, a key indicator in structural engineering. Yet, the yield …

The improvement in strength is usually accompanied by ductility loss in structural materials,
which is a long-standing conflict referred as the strength-ductility trade-off. Here we present …

High-Entropy Alloys, Second Edition provides a complete review of the current state of the
field of high entropy alloys (HEA). Building upon the first edition, this fully updated release …

Polymorphism and polymorphic transitions are attracting considerable interest because of
their significant effect on the phase stability, switchable properties, and the atomic …

Hot-deformation behaviors of an equiatomic HfNbTaTiZr refractory high entropy alloy having
BCC structure were investigated. Uniaxial compression was carried out at different …

Single-phase equiatomic CoCrFeMnNi high-entropy alloy (HEA) specimens with three
different grain sizes (0.65 μm, 2.1 μm and 105 μm) were processed by cold rolling and …

The oxidation behavior of Al x CoCrCuFeNi (x= 0, 0.5, 1, 1.5, 2) high entropy alloys are
discussed in this work. Five kinds of HEAs with nominal compositions of are prepared by …
