Computational microstructural mechanics of alloys solidified in a magnetic field

The Computational Science and Engineering Research team at Greenwich has pioneered the study of fluid flow (introduced by the presence of an external magnetic field) on the evolution of crystalline microstructure during solidification. The ultimate aim of this work is to introduce the technique to industry so that macroscopic material properties can be tailored for specific functions. To date there has been no investigation in this context, that is linking magnetic field induced microstructural changes to macroscopic properties. This research will conduct a computational parametric study of how various thermophysical or electrical properties such as mechanical yield stress and electrical conductivity can be altered (and optimised) through careful selection of the magnetic field strength, orientation and frequency. This will be achieved by designing a model that can interface with the current solidification code that predicts microstructural evolution. The new model will represent standard benchmark tests that can be validated against experimental results, attained through collaborative research projects and an ongoing literature survey.

This field of research is truly multi-disciplinary encompassing microstructure solidification, electromagnetism, fluid flow (Magnetohydrodynamics), structural mechanics and numerical analysis. Applicants are not expected to have significant knowledge of all of these disciplines, but should have a solid grounding in at least one and basic understanding of another.
