For most metallic materials, surface hardening via modifying the near-surface microstructure
is an effective method for improving mechanical properties. Among these processes, laser …

Precipitation strengthening is one of the most promising methods to develop magnesium
(Mg) alloys. However, the nerve-wracking fact is that the cast Mg alloys always have coarse …

We studied the deformation behavior of CrFeCoNi high-entropy alloy by in situ neutron
diffraction at room temperature, intermediate low temperature of 140 K, low temperatures of …

Multiphase CrMnFeCoNi high-entropy alloys (HEAs) were prepared by a powder metallurgy
process combining mechanical alloying (MA) and vacuum hot-pressing sintering (HPS). The …

Precipitate hardening is considered as an effective method to strengthen High-and medium-
entropy alloys (HEAs and MEAs), especially the recently developed Co-free HEAs/MEAs. In …

Novel high-entropy alloys (HEAs) of the Ti (30–x) VCrNb (x)(x= 0, 5, 10, 15, and 20 at%)
system were designed, synthesized, and characterized. The microstructural features were …

The microstructure and mechanical properties of dissimilar laser beam welded joint between
CrMnFeCoNi alloy and 316LN stainless steel was investigated. The results showed that the …

Here, bulk CoCrFeMnNi high-entropy alloy was prepared via laser melting deposition, and
its microstructure and mechanical properties at room and cryogenic temperature were …

High-entropy alloys (HEAs) with a face-centered cubic (FCC) lattice usually exhibit decent
ductility but low yield strength at cryogenic temperatures. In order to address this issue, in …

The low yield strength of the equiatomic CoCrFeMnNi high-entropy alloy (HEA) at ambient
temperature severely limits its future application as engineering materials. Here, a …
