Statistical Crystal Plasticity Model Advanced for Grain Boundary Sliding Description
Crystals, 2020 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.

Crystals, 2017 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 ...

, 1991 The present document is a progress report describing the work accomplished to date during the second year of our four-year grant (February 15, 1990--February 14, 1994) to study grain boundaries. The research was focused on the following three major efforts: Study of the atomic structure of grain boundaries by means of x-ray diffraction, transmission ...

Grain-boundary topological superconductor
Communications Physics, 2023 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.

The mechanisms of grain growth of Mg alloys: A review
Journal of Magnesium and Alloys, 2022 Grain growth directly influences the plasticity and strength of Mg alloys. As the grain size decreases from the microscale to the nanoscale, the plasticity of Mg alloys continually increases, whereas the strength first increases and later decreases ...
