The combination of multiple-principal element materials, known as high-entropy materials
(HEMs), expands the multi-dimensional compositional space to gigantic stoichiometry. It is …

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

Shock-induced deformation and fracture in single-crystalline and nanocrystalline
CoCrFeMnNi high-entropy alloys (HEAs) under different shock intensities are investigated …

Alloying has been very common practice in materials engineering to fabricate metals of
desirable properties for specific applications. Traditionally, a small amount of the desired …

In this study, the dynamic compressive response behavior of a body-centered cubic (BCC)
single-phase TiZrNbV refractory high-entropy alloy (RHEA) was investigated under impact at …

The strength-ductility trade-off dilemma is perennially problematic in the materials science
community. In particular, the attainability of high tensile strength and large elongation is …

The equiatomic face-centered cubic high-entropy alloy CrMnFeCoNi was severely deformed
at room and liquid nitrogen temperature by high-pressure torsion up to shear strains of about …

The gradient nano-grained (GNG) structures achieve a combination of high strength and
ductility compared with homogeneous nano-grained structures. In order to study the …

Abstract We applied Simmons–Balluffi methods, positron measurements, and neutron
diffraction to estimate the vacancy of CoCrFeNi and CoCrFeMnNi high-entropy alloys …

Grain boundaries (GBs) of nanograined metals are prone to migrate when subjected to
mechanical loading. In this study, nanograined pure nickel samples with an average grain …
