Course Objective

The present course is intended to introduce Metastability and Metastable Materials and non-equilibrium processes employed to synthesize such materials. General principals of non-equilibrium processing, bottom-up (starting from atoms and ions) and top-down (starting from bulk) approach in synthesis of metastable materials will be outlined. Thermodynamic considerations involved in non-equilibrium processing will be discussed. Microstructural features offered by non-equilibrium processing will be covered. Industrial applications of metastable materials will be introduced.
