Grain-boundary topological phase transitions
TLDR
It is demonstrated that GBs undergo a finite-temperature topological phase transition of the Kosterlitz–Thouless (KT) type, which leads to abrupt changes in the behavior of GB migration, GB sliding, and roughening. Expand
Interdiffusion in bimetallic Au–Fe nanowhiskers controlled by interface mobility
Abstract Nanoscale interdiffusion at the heterophase interfaces is the elementary process that controls solid-solid phase transformations and intermixing in multilayers. Here, we provide a directExpand
The grain boundary mobility tensor
TLDR
It is argued that the mobility is, in general, a tensor (classically, it is a scalar) and determine all of its components and demonstrated that stress generation during GB migration necessarily slows grain growth and reduces GB mobility in polycrystals. Expand

Energetic, structural and mechanical properties of terraced interfaces
Abstract Taking the well-understood Cu-Ni {111} semi-coherent interface as a prototype, we demonstrate an important, yet long-been-overlooked, size effect on the properties of terraced interfaces —Expand
In situ atomistic observation of disconnection-mediated grain boundary migration
TLDR
The atomistic mechanism of disconnection-mediated GB migration in different gold nanostructures is revealed using a state-of-art in situ shear testing technique combined with molecular dynamic simulations. Expand
Determination of the structure of α-β interfaces in metastable β-Ti alloys
Abstract The crystallography and structure of the interfaces formed between refined hexagonal close packed (hcp) α precipitates and the body centered cubic (bcc) β matrix in a solution-treated andExpand
Grain boundary shear coupling is not a grain boundary property
Abstract Shear coupling implies that all grain boundary (GB) migration necessarily creates mechanical stresses/strains and is a key component to the evolution of all polycrystalline microstructures.Expand
Grain-Boundary Kinetics: A Unified Approach
Grain boundaries (GBs) are central defects for describing polycrystalline materials, and playing major role in a wide-range of physical properties of polycrystals. Control over GB kinetics providesExpand
