Grain-Boundary Topological Phase Transitions
Kongtao Chen, David J. Srolovitz, Jian Han
The formation and migration of disconnections (line defects constrained to the grain boundary (GB) plane with both dislocation and step character) control many of the kinetic and d…
Distribution of Topological Types in Grain-Growth Microstructures
Emanuel A. Lazar, Jeremy K. Mason, Robert D. MacPherson +1
An open question in studying normal grain growth concerns the asymptotic state to which microstructures converge. In particular, the distribution of grain topologies is unknown. We…
On the Temperature Dependence of Grain Boundary Mobility
Kongtao Chen, Jian Han, David J. Srolovitz
The grain boundary (GB) mobility relates GB velocity to the thermodynamic driving forces and is central to our understanding of microstructure evolution in polycrystals. Recent mol…
Power-law scaling for solid-state dewetting of thin films: an Onsager variational approach
Wei Jiang, Xianmin Xu, Weizhu Bao +1
We examine the kinetics of surface diffusion-controlled, solid-state dewetting by consideration of the retraction of the contact in a semi-infinite solid thin film on a flat rigid…
