Fatigue and fracture of nanostructured metals and alloys
Metals and alloys with nanoscale structural features (such as grain size or twin thickness<
100 nm) exhibit exceptional strength and unusual deformation mechanisms. But, the …

On the role of Cu-Zr amorphous intergranular films on crack growth retardation in nanocrystalline Cu during monotonic and cyclic loading conditions
In the present study, molecular dynamics simulation was used to investigate the influence of
amorphous intergranular films (AIF) and its thickness on possible crack retardation in …

Revealing inconsistencies in X-ray width methods for nanomaterials
Since the landmark development of the Scherrer method a century ago, multiple generations
of width methods for X-ray diffraction originated to non-invasively and rapidly characterize …

The heterogeneous nature of mechanically accelerated grain growth
While grain growth is traditionally viewed as a purely thermally driven process,
nanocrystalline metals can undergo grain growth under mechanical loads, even at room …

Grain boundaries dependence of plastic deformation in nanocrystalline Cu film investigated by phase field and molecular dynamics methods
M Zhang, T Xu, L Fang - Materials Chemistry and Physics, 2020 - Elsevier
The phase filed model was used to create the nanocrystalline (NC) Cu film with more natural
grain boundaries (GBs) for molecular dynamics (MD) simulation. The results obtained by …

Atomic mechanism of cyclic healing effect in dual-phase metastable high entropy alloy
While many experiments and simulations on the high entropy alloy have focused on the
deformation mechanisms under monotonic loading, the cyclic deformation behaviors remain …
