There are abundant studies on deformation mechanisms in metallic materials dominated by
grain boundaries and twin boundaries. In comparison, the influence of stacking faults on …

Dislocation interaction with and accumulation at twin boundaries have been reported to
significantly improve the strength and ductility of nanostructured face-centered cubic (fcc) …

A density functional theory–phase field dislocation dynamics model is used to study stress-
induced emission of defects from grain boundaries in nanoscale face-centered cubic (fcc) …

We report a grain boundary formation mechanism in face-centred cubic metals with low
stacking fault energies. Severe plastic deformation produces primary nano-twins with a twin …

Deformation mechanisms in metals deformed to ultrahigh strains are analyzed based on a
general pattern of grain subdivision down to structural scales∼ 10nm. The materials …

Bulk nanostructured (NS) materials processed by severe plastic deformation (SPD) have
received considerable attention for several decades. The physical origin of this processing …

Numerous recent studies have focused on the effects of grain size on deformation twinning
in nanocrystalline fcc metals. However, grain size alone cannot explain many observed …

The interactions between dislocations (dislocations and deformation twins) and boundaries
(grain boundaries, twin boundaries and phase interfaces) during deformation at ambient …

The strengthening effect of twins in nanocrystalline metals has been reported both in
experiment and simulation. While twins are mostly considered as effective barriers to …

This work presents a mechanism of deformation-twin-induced grain boundary failure, and
demonstrates the mechanism using molecular dynamics simulations. Deformation twinning …
