RESEARCH INTERESTS

  • Thermodynamics and kinetics of phase transformation in metallic alloys; behavior of metastable
    phases.
  • Interfacial phenomenon in materials: solute segregation at grain boundaries and interphase
    boundaries.
  • Microstructure-mechanical/magnetic/electronic property relationships in materials.
  • Influence of non-equilibrium material processing such as solid-phase processing on microstructure
    and properties of materials
  • Degradation of materials during exposure to extreme environments such as irradiation and gas or
    liquid reactions with surfaces (corrosion).
