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 …

Bulk nanostructured (NS) materials processed by severe plastic deformation (SPD) have
received considerable attention for several decades. The physical origin of this processing …

Molecular dynamics (MD) simulations confirm that normal grain boundary (GB) motion must
often be coupled to tangential translation of grains and will then produce shear deformation …

New perspectives on the phase field approach in modeling deformation and fracture at the
fundamental defect level are reviewed. When applied at sub-angstrom length scales the …

Conventional models for grain growth are based on the assumption that grain boundary
(GB) velocity is proportional to GB mean curvature. We demonstrate via a series of …

Current developments in kinetic and thermodynamic stabilization of grains in nanostructured
metals, alloys, and compounds are generalized and discussed in detail. As applied to the …

Abstract Al-Zn-Cu-Mg alloys (eg, AA7075) have been widely used to form structural
components in aerospace and other industries. For Al-Zn-Cu-Mg alloys, although dynamic …

We review how phase-field models contributed to the understanding of various aspects of
crystal nucleation, including homogeneous and heterogeneous processes, and their role in …

Grain boundary (GB) migration associated with grain growth and recrystallization
encounters lattice defects frequently, while the atomistic mechanisms of GB-defect …

We report on molecular dynamics simulations of an isolated cylindrical grain in copper
shrinking under capillary forces. At low temperatures, the coupling between grain boundary …
