Subject syllabus:

1. Significance of studies on structure property relationships in engineering materials. 2. Atomic structure in solids. Wave mechanics model of atom. Electronic structure of elements. Periodic table of elements. Binding in solids (ion, covalent, metallic, Van der Waals, mixed). 3. Basics of crystallography. Theory of repetition, translation periodicity of crystals, elementary cell, space lattice, basic principles of reciprocal lattice, symmetry elements of crystals, crystal systems, laws of geometrical crystallography. 4. Crystal structures of elements (molecular orbites, band theory, structures of closed packed atoms, structures with directional binding). Allotropy. Polar structures. Binary alloys structures (solid solutions, ordered phases, electron compounds, alloys with dominant size factor, compounds of transitive elements with variable composition, interstitial compounds). 5. Point defects in metals and alloys. Equilibrium concentration of point defects. Formation of non-equilibrium concentration of point defects (quenching, plastic deformation). Recovery of excessive point defects. Diffusion in metallic systems. Basic diffusion equations (I. and II. Fick´s law). Atomic theory of diffusion, mechanisms of diffusion of substitutional and interstitial atoms. Selfdiffusion. Effect of temperature - thermal activation. 6. Paths of high diffusivity (diffusion along grain boundaries and free surfaces). Diffusion in alloys, diffusion at concentration gradient, practical examples of diffusion. 7. Line defects in crystal lattice - dislocations. Basic classification, definition Burger´s vector, movement of dislocations, forces affecting dislocations, energy of dislocation, stacking faults. 8. Interactions between dislocations: crossing of dislocations, movement of jogs on dislocations, cross slip, climbing, dislocation reactions, dislocation density, dislocation sources. Dislocations in important crystal structures. FCC: dislocation reactions, Thompson tetraedra, stacking faults and partial dislocations. 9. HCP: dislocation reactions, stacking faults and partial dislocations. BCC: dislocation reactions, stacking faults and partial dislocations. Interaction of dislocations with point defects. Dislocations in systems with long-range order. Grain and subgrain boundaries, interfaces between phases. 10. Phase transformations. Solidification of metals and alloys. Crystal growth in pure metals. Solidification of castings (ingots) and conticasts. 11. Phase transformations in solids, classification. Diffusive transformations, precipitation, ordering, eutectoid reaction, massive transformations. 12. Diffusionless transformations. Kinetics of transformations. Crystallography of martensitic transformation in steels. 13. Deformation strengthening. Strengthening curves of FCC, HCP and BCC single crystals. Theory of strengthening of pure metals. Plastic deformation of polycrystals. Substitutional strengthening. Precipitation strengthening: coherent and non-coherent particles. 14. Fracture mechanisms. Griffith´s criterion. Stages of fracture process. Brittle fracture. Ductile fracture. Stress corrosion fracture. Fatigue fracture. Creep fracture.
