Refining a metal's grain size can result in dramatic increases in strength, and the magnitude
of this strengthening increment can be estimated using the Hall–Petch equation. Since the …

Micro-and nanoscale materials have remarkable mechanical properties, such as enhanced
strength and toughness, but they usually display sample-to-sample fluctuations and size …

AC Eringen has been a most active advocate of the nonlocal theory of continua finding many
applications for it in solid, fluid, and electromagnetic media. His work is also used …

A new crystal plasticity model based on the deformation mechanism for ultrafine-grained/
nanocrystalline face-centered cubic (FCC) metals was developed. The deformation …

For the first time, high quality bulk nanocrystalline (nc) fcc metals, with least amounts of
imperfections, exhibiting high strength and ductility at room and different temperatures …

Many studies have shown that the outstanding mechanical properties of surface nano-
crystallized (SNC) materials were primarily attributed to the grain size gradient (GSG) region …

Grain boundary influence on material properties becomes increasingly significant as grain
size is reduced to the nanoscale. Nanostructured materials produced by severe plastic …

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 …

A novel dislocation-density-based crystal plasticity model for nanocrystalline face-centered
cubic metals is developed based on the thermally-activated mechanism of dislocations …

A mechanical constitutive relationship is the basis for the design and application of structural
materials, and the establishment of a mechanical constitutive relationship generally relies on …
