I am a graduate student with interest in modeling microstructural evolution accompanying phase transformations. In my current research I have developed a cellular-automaton based model which simulates transformations of interdendritic phases occurring at the secondary dendrite arm spacing length scale and a particle size distribution based model which simulates precipitation of nano-sized dispersoids which have been coupled to simulate microstructural evolution during the homogenization of 6xxx and 7xxx aluminum alloys. The models derive the thermodynamic data for these alloys from Thermo-CalcTM. I have validated the numerical results with experiments which improve the homogenization schedules and compositions yielding microstructure which could be easily extruded. My Master’s thesis was on a first principle study of the morphology and deformation mechanism of precipitates in Al-Sc-Zr alloys. With experience in microstructure modeling and its implications on deformation at atomistic and meso-scale, I am looking forward to develop multiscale models to solve material problems.
