Phase-field simulations of partial melts in geological materials
Computers & Geosciences, 2009A diffuse interface description based on a multi-phase-field model for geological grain microstructures is introduced, especially useful in the treatment of partially molten structures. Each grain as well as different phases are represented by individual non-conserved order parameters, the phase fields @f"@a, which are defined on the complete ...

Phase field simulations of the ferroelectric materials
2016In the PhD research, phase field simulations were conducted to study the polarization behavior and properties of ferroelectric materials. Four aspects of ferroelectric materials were simulated, which are 1) electrocaloric effect, 2) the influence of dislocation walls, 3) fracture; and 4) the influence of {111} twins.

Extreme Scale Phase-Field Simulation of Sintering Processes
2019 IEEE/ACM 10th Workshop on Latest Advances in Scalable Algorithms for Large-Scale Systems (ScalA), 2019The sintering process, which turns loose powders into dense materials, is naturally found in the formation of glaciers, but is also the indispensable process to manufacture ceramic materials. The dynamically evolving microstructure, which is established during this process, largely influences the resulting material properties.

Phase field simulations of ferroelectric materials
2014Ferroelectric materials have become preferred materials in a wide variety of electronic and mechatronic devices due to their pronounced dielectric, piezoelectric, and pyroelectric properties. The material macroscopic properties are related to the microscopic domain structure of the materials.

The phase field simulation of autocatalytic nucleation
2017Precipitation of metastable θ′ phase is a well known process that underlies age-hardening of Al-Cu alloys. The strength acquired is very sensitive to the morphology and spatial distribution of θ′, with the peak hardness corresponding to a fine distribution of precipitates with high length-to-thickness aspect ratio.

Phase Field Crystal Simulator (PFC_Simulator).
2019Программа предназначена для расчета процессов кристаллического роста, описываемых моделью кристаллического фазового поля. Уравнение кристаллического фазового поля (Phase Field Crystal - PFC) в гиперболической постановке позволяет описывать высокоскоростные структурно-фазовые превращения из неустойчивого или метастабильного состояния, является ...
