Research Focus

  • Diffusion phenomena in metals and compounds including multi-principal element alloys and compositionally-complex alloys
    The prime focus is on the development of tracer/interdiffusion couple method to determine composition-dependent tracer diffusion coefficients in multi-component alloys. Further directions are: Nanocrystalline and ultra-fine grained materials; Molecular dynamic simulations of diffusion phenomena; Anomalously fast ionic conductivity of grain boundaries in superionic oxide films; Correlation factors in impurity diffusion in ordered intermetallics
  • short circuit diffusion in metals and alloys
    Fundamental problems of grain boundary diffusion and segregation in metallic materials, especially in bicrystals with perfectly characterized grain boundaries, are here in the focus. The diffusion (mainly radiotracer) investigations are used as source of unique information on structure and thermodynamic state of internal interfaces in materials and their evolution with stress and strain.
  • impact of deformation on diffusion processes in materials
    I am primary interested in experimental studies of kinetic properties of metallic materials under extreme load conditions. The severe plastic deformation is used to produce ultra-fine grained state of materials. As a result, the so-called ultra-fast diffusion paths are created in the materials which are suggested to be responsible for the attractive properties and unique combinations of these properties in such materials.
  • thermodynamics of grain boundary segregation
  • diffusion phenomena in as-cast and deformed bulk metallic glasses
    Main focus is on diffusion properties of shear bands in metallic glasses and their relation to thermodynamic and mechanical properties of the glasses
  • Impact of external fields (magnetic / elastic ) on diffusion; diffusion under plastic deformation
