Research:Yuri Mishin

Yuri Mishin works in the areas of solid state physics and materials science, particularly on the theory and atomistic modeling of metallic materials. He is especially interested in physical properties of materials interfaces, atomic diffusion, thermodynamics and the mechanical behavior of crystals. His research is focused on metals, alloys and intermetallic compounds. Many them have important technological applications, such as high-temperature high-strength structural materials for aerospace technologies, electronic materials, and functional materials for nanotechnology. Such applications require a fundamental understanding of the physical mechanisms governing the structure-property relationships in the materials. The modeling and simulation method used by Dr. Mishin include molecular dynamics with classical potentials, various Monte Carlo schemes, phase-field modeling and other atomistic and continuum approaches. Currently Dr. Mishin has external funding to support a post-doctoral research associate and several graduate students, and he seeks to involve more students in this work. Specific areas of his research include:

Models of atomic interaction in materials.
Development of semi-empirical many-body interatomic potentials from experimental data and first-principles calculations.
Atomic structure and physical properties of interfaces in materials, including grain and inter-phase boundaries.
Interface motion, segregation, chemical reactions and cohesion.
Phase transformations at interfaces, faceting, melting and pre-melting.
Atomistic theory and modeling of interfacial kinetics in metallic materials.
Relationships between interfacial structure, chemistry, and diffusion.
Plastic deformation and fracture of metals, alloys and ordered intermetallic compounds.
Role of grain boundary sliding and cleavage.
