Pathway to lowest-energy structures and stress relaxation for the surface triple junction verified by machine learning
Yuan Fang, Ipen Demirel, Xiaopu Zhang +3
The behavior of surface triple junctions (STJ) at emergent grain boundaries on free surfaces is critical to the microstructure evolution, and therefore to the stability of the next…

Wedge disclination description of emergent core-shifted grain boundaries at free surfaces
Xiaopu Zhang, Ipen Demirel, John J. Boland
Emergent grain boundaries at free surface control material properties such as nanomaterial strength, catalysis, and corrosion. Recently the restructuring of emergent boundaries on…
