New phase-field model for polycrystalline systems with anisotropic grain boundary properties
In this paper, a new methodology is presented to inlude anisotropic grain boundary properties in a phase-field model. The new approach is thermodynamically consistent and gives accurate control of the inclination and misorientation of grain boundary ...

Grain boundary dislocations in plane matching grain boundaries [PDF]
Plane matching (PM) boundaries are defined as boundaries in which a single stack of planes of indices (hkl) in each crystal adjoining the boundary is either parallel, or nearly parallel, and where no other significant lattice matching exists. A search was made (by transmission electron microscopy) for possible intrinsic secondary grain boundary ...

Statistical Crystal Plasticity Model Advanced for Grain Boundary Sliding Description
Grain boundary sliding is an important deformation mechanism, and therefore its description is essential for modeling different technological processes of thermomechanical treatment, in particular the superplasticity forming of metallic materials.

Grain-boundary topological superconductor
Majorana zero modes (MZMs) are of central importance for modern condensed matter physics and quantum information due to their non-Abelian nature, which thereby offers the possibility of realizing topological quantum bits.

Non-uniform grain boundary sliding can induce strain and rotation incompatibilities at perfectly planar interfaces. Explicit analytic expressions of stress and lattice rotation jumps are thus derived at a planar interface in the general framework of ...

Effect of serrated grain boundary on stress corrosion cracking of Alloy 600
The effect of a serrated grain boundary on stress corrosion cracking (SCC) of Alloy 600 was investigated in terms of improvement of SCC resistance. Serrated grain boundaries and straight grain boundaries were obtained by controlled heat treatment.
