Subject syllabus

1. Fundamentals of thermodynamics of solids; systems, components, phases; states of thermodynamic systems; Gibbs phase law.
2. Internal structure of solids, crystal structure failures.
3. One-component systems; solid state solidification, critical nucleation size (stable, unstable nucleation), homogeneous vs. solid state heterogeneous nucleation; solid state phase transformations.
4. Two-component systems and their equilibrium diagrams, basic types - system with unlimited solid solubility, system with eutectic, peritectic reaction; system with eutectoid reaction.
5. More complex two-component systems with solid state phase transformations and intermediate phases.
6. Iron-carbon system (Fe-C); metastable, stable diagram; basic types of reactions; phase description of the metastable diagram.
7. Basic structures in metastable Fe-C system; calculations of phase and structure composition in metastable Fe-C system.
8. Stable Fe-C system, differences from metastable system; graphitic cast iron, classification, basic characteristics.
9. Phase transformations of austenite during cooling - diffusion and partially diffusion transformations, basic characteristics of ferrite, pearlite, bainite.
10. Phase transformations of austenite during cooling - diffusionless transformations; basic characteristics of martensite.
11. Basic types of failure of technical materials - ductile, brittle failure. Methods of assessing the resistance of materials to brittle failure. Defects in materials - crack growth mechanisms, critical crack size; Griffith criterion, Griffith-Orowan criterion. Fracture toughness.
12. Basic mechanisms of degradation of materials in the oil industry - hydrogen embrittlement, sulphide stress cracking.
