Title: Phase-field modeling of microstructure for designing high-performance industrial alloys

Abstract: Phase-field approach is a relatively young interdisciplinary technique still being developed to predict the complex chain of chemistry, structure, processing, and property in materials. To make reliable predictions of materials response during service conditions, we should realize that the properties of a material and its integrity are controlled by the structure of the alloy in Micron to Nano scales. In this talk, I review the mathematical foundations of the phase-field approach and give examples of the calculated microstructures from real world alloys. These include the calculated microstructures for (1) the solder materials in electronic 3D Integrated Circuits (3D ICs), (2) thermoelectric materials for electricity generation through low-grid waste heat sources, potentially used in space exploration applications, (3) ultra-hard coating materials and many other examples. Phase-field approach can be very expensive and supercomputing knowledge is a plus. The goal of my talk is to introduce you to the interdisciplinary field of phase-field modeling where excellent mathematical and engineering skills are required to help design novel materials for novel applications.
