This paper reports a new type of unique gradient microstructure (ie, fine-grained core and
coarse-grained surface regions) fabricated using a continuous severe plastic deformation …

The FCC structured CoCrFeMnNi high entropy alloy (HEA) has attracted great attention due
to its excellent ductility and strain hardening ability, but the lowest yield strength is …

Materials can be made strong, but as such they are often brittle and prone to fracture when
under stress. Inspired by the exceptionally strong and ductile structure of byssal threads …

In the present study, ultrasonic impact treatment was applied to promote the as-cast Al x
CoCrFeMnNi (x= 0, 0.5, 1.0 and 1.5) high entropy alloys, and the microstructures, phase …

In this paper, we designed a novel non-equiatomic medium-entropy alloy (MEA) with
heterogeneous grain structures (HGS) and dual-morphology L1 2 nano-precipitates through …

Gradient structure (GS) is beneficial for metal materials to obtain excellent comprehensive
properties of strength and toughness, since the geometrically necessary dislocations …

The microstructure, hardness and tensile properties have been studied in copper processed
by high pressure surface rolling (HPSR) both in the as-deformed condition and after …

Gradient nano-grained (GNG) metals are an emerging class of heterogeneous structured
materials with extraordinary mechanistic performances and unnatural plasticity mechanisms …

The application of high entropy alloy (HEA) as coating materials has become a research
hotspot. The combination of laser cladding technology and ultrasonic impact treatment (UIT) …

Gradient structured (GS) metals can simultaneously achieve high strength and high ductility,
which is the pursuit of structural materials. Abundant studies have pointed out that significant …
