Accelerating grain boundary modelling and simulation by automated pre-evaluation of the irreducible macroscopic representation
Wei Wan
A major challenge in the modelling and simulation of grain boundaries (GBs) is the conflict between the system size and computation capability, which inherently restricts the compu…
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…
Energy function for grain boundary plane orientation fundamental zone
Wei Wan
The success of grain boundary (GB) plane orientation fundamental zone (FZ) has connected GB structures across multiple crystallographic characters with their properties in a unique…
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…
