Atomic structure and mechanical response of coincident stacking faults in boron suboxide
(Materials Research Letters, 2019)
We report the atomic structure of coincident stacking faults (SFs) in superhard boron suboxide (B6O) by combining annular bright field scanning transmission electron microscopy and quantum mechanics (QM) simulations. ...
Grain boundary sliding and amorphization is responsible for the reverse Hall-Petch relation in superhard nanocrystalline boron carbide
(American Physical Society, 2018)
The recent observation of the reverse Hall-Petch relation in nanocrystalline ceramics offers a possible pathway to achieve enhanced ductility for traditional brittle ceramics via the nanosize effect, just as nanocrystalline ...
