Severe plastic deformation (SPD) is effective in producing bulk ultrafine-grained and
nanostructured materials with large densities of lattice defects. This field, also known as …

Superplasticity describes a material's ability to sustain large plastic deformation in the form
of a tensile elongation to over 400% of its original length, but is generally observed only at a …

Ultrafine-grained and heterostructured materials are currently of high interest due to their
superior mechanical and functional properties. Severe plastic deformation (SPD) is one of …

Abstract High Entropy Alloys (HEAs) are a new class of multi-component alloys with
excellent tensile strength-ductility combination. Their yield strength levels, however, are still …

Alloying is an effective strategy to tailor microstructure and mechanical properties of metallic
materials to overcome the strength-ductility trade-off dilemma. In this work, we combined a …

An equiatomic VCoNi medium-entropy alloy possesses high sensitivity to grain-boundary
strengthening, achieved by severe lattice distortions. Its ultrafine-grain structure enables 1.5 …

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 …

Abstract A series of (CoCrNi) 100–x Gd x (x= 0/0.1/0.3/0.5/1.0) medium entropy alloys
(MEAs) was fabricated by high-vacuum arc melting. The effects of rare-earth element, Gd …

High-entropy alloy coatings (HEAC) exhibit good frictional wear and corrosion resistances,
which are of importance for structure materials. In this study, the microstructure, surface …

Abstract In this study, CoCrNi MEAs added with different silicon contents (0, 0.1, 0.2 for
molar ratio) were prepared by arc melting. The cold rolled and annealed microstructural …
