The structure and migration of heavily irradiated grain boundaries and dislocations in Ni in the athermal limit
Ian Chesser, Peter M. Derlet, Avanish Mishra +6
The microstructural evolution at and near pre-existing grain boundaries (GBs) and dislocations in materials under high radiation doses is still poorly understood. In this work, we…

On the Variability of Grain Boundary Mobility in the Isoconfigurational Ensemble
Anqi Qiu, Ian Chesser, Elizabeth Holm
Recent grain growth experiments have revealed that the same type of grain boundary can have very different mobilities depending on its local microstructure. In this work, we use mo…

Understanding the anomalous thermal behavior of sigma 3 grain boundaries in a variety of FCC metals
Ian Chesser, Elizabeth Holm
We present a case study of the complex temperature dependence of grain boundary mobility. The same general incoherent twin boundary in different FCC metals is found to display anti…
