Abstract High-entropy alloys (HEAs), also known as multi-principal element alloys or multi-
component alloys, have been the subject of numerous investigations since they were first …

Grain size has a profound effect on the mechanical response of metals. Molecular dynamics
continues to expand its range from a handful of atoms to grain sizes up to 50 nm, albeit …

The control of interfaces in engineered nanostructured materials has met limited success
compared with that which has evolved in natural materials, where hierarchical structures …

Solute segregation at grain boundaries (GBs) is emerging as an alloy design tool, uses of
which include the stabilization of nanocrystalline alloys. To predict the equilibrium …

The brittle–ductile transition (BDT) widely exists in the manufacturing with extremely small
deformation scale, thermally assisted machining, and high-speed machining. This paper …

Multicomponent alloying can be utilized to enhance the thermal stability of nanocrystalline
alloys. The grain boundary energy can be reduced significantly via both bulk and grain …

Nanostructuring is a commonly employed method of obtaining superior mechanical
properties in metals and alloys. Compared to conventional polycrystalline counterparts …

In this paper first a generally valid model is derived from the two fundamental equations of
Gibbs for temperature and composition dependences of all types of interfacial energies. This …

The ability of amorphous intergranular films to mitigate damage formation at grain
boundaries is studied with molecular dynamics simulations. We find that such films can alter …

Abstract Nanocrystalline Cu-3 at.% Zr powders with~ 20 nm average grain size were created
with mechanical alloying and their thermal stability was studied from 550–950° C. Annealing …
