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 ...

New phase-field model for polycrystalline systems with anisotropic grain boundary properties
Materials & Design, 2022 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 ...

Numerical simulation of grain-size effects on creep crack growth by means of grain elements [PDF]
, 1998 The effect of grain size on creep crack growth is investigated by means of a numerical technique in which the actual crack growth process is simulated in a discrete manner by grain elements and grain boundary elements.

Grain boundaries in vortex matter [PDF]
Physical Review B, 2005 We explore the statistical properties of grain boundaries in the vortex polycrystalline phase of type II superconductors. Treating grain boundaries as arrays of dislocations interacting through linear elasticity, we show that self-interaction of a deformed grain boundary is equivalent to a non-local long-range surface tension.

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.
