Simulation of Dendritic-Eutectic Growth with the Phase-Field Method
Acta Materialia, 2023 Solidification is an important process in many alloy processing routes. The solidified microstructure of alloys is usually made up of dendrites, eutectics or a combination of both. The evolving morphologies are largely determined by the solidification process and thus many materials properties are dependent on the processing conditions.

Phase Field Methods for Binary Recovery [PDF]
, 2014 We consider the inverse problem of recovering a binary function from blurred and noisy data. Such problems arise in many applications, for example image processing and optimal control of PDEs. Our formulation is based on the Mumford-Shah model, but with a phase field approximation to the perimeter regularisation.

Bubble flow analysis using multi-phase field method [PDF]
EPJ Web of ConferencesIn simulations of gas-liquid two-phase flows using conventional interface capture methods, we observed that when bubbles come close to each other, they tend to merge numerically, despite experimental evidence indicating that they would repel each other ...

Austenite grain growth simulation considering the solute-drag effect and pinning effect
Science and Technology of Advanced Materials, 2017 The pinning effect is useful for restraining austenite grain growth in low alloy steel and improving heat affected zone toughness in welded joints. We propose a new calculation model for predicting austenite grain growth behavior.

Effect of Number of Variants of Zirconium Hydride on Grain Growth of Zirconium
Metals, 2020 The microstructure characteristics of Zr-hydride in Zr are important concerns in metallurgy and nuclear engineering. In particular, it is known that the correlation between hydride and the grain boundary microstructure has a great influence on properties.
