Fatigue and fracture of nanostructured metals and alloys

L Lu, Q Pan, K Hattar, BL Boyce - MRS Bulletin, 2021 - Springer
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

S Pal, KV Reddy, C Deng - Computational Materials Science, 2019 - Elsevier
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

C Kunka, BL Boyce, SM Foiles, R Dingreville - Nanoscale, 2019 - pubs.rsc.org

The heterogeneous nature of mechanically accelerated grain growth

EY Chen, P Hamilton, BL Boyce… - Journal of Materials …, 2022 - Springer
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

P Wang, Z Song, Q Li, H Wang - Journal of Alloys and Compounds, 2021 - Elsevier
