Automated Analysis to Reveal Grain Boundary Phase Microstructures
R. Daniel Moore, Ian S. Winter, Robert E. Rudd +2
We develop a method for analyzing grain boundary (GB) microstructures that identifies distinct interfacial phases and the dislocation line defects separating them. Similar to bulk…
The Dislocation Content of Triple Junctions
Ian S Winter, R. Daniel Moore, R. E. Rudd +2
Triple junctions, line defects formed by the intersection of different grain boundaries, exist within all polycrystalline materials. While it has long been recognized that triple j…
Mapping strain and structural heterogeneities around bubbles in amorphous ionically conductive BiO
Ellis Rae Kennedy, Stephanie M. Ribet, Ian S. Winter +5
While amorphous materials are often approximated to have a statistically homogeneous atomic structure, they frequently exhibit localized structural heterogeneity that challenges si…
Quantifying and Visualizing the Microscopic Degrees of Freedom of Grain Boundaries in the Wigner-Seitz Cell of the Displacement-Shift-Complete Lattice
Ian S. Winter, Timofey Frolov
We introduce a grain boundary (GB) translation vector, , to describe and quantify the domain of the microscopic degrees of freedom of GBs. It has long been recogni…
