Decomposition of low-angle grain boundaries
Wei Wan, Changxin Tang, Eric R Homer
Grain boundaries (GBs) merge and grains disappear during microstructure evolution. However, the Peach-Koehler model predicts that particular stress states may reverse such a proces…
Decomposition of general grain boundaries
Wei Wan, Junwen Deng, Changxin Tang
As a central part of microstructure evolution, grain boundary (GB) migration is believed to be both monolithic and unidirectional. But here, we introduce the concept of GB decompos…
Can we predict mixed grain boundaries from their tilt and twist components?
Wei Wan, Changxin Tang, Eric R. Homer
One of the major challenges towards understanding and further utilizing the properties and functional behaviors of grain boundaries (GB) is the complexity of general GBs with mixed…
Structures and energies of computed silicon (001) small angle mixed grain boundaries as a function of three macroscopic characters
Wei Wan, Changxin Tang
Understanding how dislocation structures vary with grain boundary (GB) characters enables accurate controls of interfacial nano-patterns. In this atomistic study, we report the str…
No vortex in straight flows -- on the eigen-representations of velocity gradient
Xiangyang Xu, Zhiwen Xu, Changxin Tang +2
Velocity gradient is the basis of many vortex recognition methods, such as Q criterion, criterion, criterion, criterion and criterion, etc.. Except the $λ_…
