Course Objectives
After successfully completing this course the student will able to:
1. Explain the fundamentals of the free energy of solid solutions; the stable state of an alloy; homogeneous and heterogeneous equilibrium;
2. Explain the fundamentals of statistico-thermodynamical theory of alloys, quantum-mechanical model of interatomic interactions and total crystal energy in the nearly free electron model;
3. Explain the pseudopotential theory (PP) of interatomic interactions: potential seen by an atomic electron; dielectric screening; the concepts of pseudoatom and pseudopotential; the band structure energy of metals and alloys; total internal energy of alloys.
4. Explain and apply the PP theory for crystal structure stability calculations of elements; theory of phase boundaries and structure stability of the alloy systems; ordered phases, their structures and existence conditions.
Course Content
Theoretical basis of structure of solid solutions; Quasi-chemical statistico-thermo dynamical and quantum mechanical theory of interatomic interactions in metals and alloys; theory of crystal-structure stability; Energy of phase boundaries; Ordered phases, their structure and existence conditions; Interatomic interaction in the fiber reinforced metal matrix composites.
Course Learning Outcomes
(a) An ability to establish important relationship between macroscopic (bulk) and microscopic (atomic) parameters of ordered/disordered crystalline alloy systems;
(b) An ability to use various computer programs, for calculation of interatomic interaction potentials, ordering energies, etc. in order to establish important relationship between internal atomic structure and bulk physico-chemical properties of ordered/disordered crystalline alloy systems;
(c) The course will bridge the gap between line of courses in the graduate program on Physics of Materials (METE 509, METE 510) and on courses offered on physical metallurgy.
