The physical background of processes encountered in production and thermo-mechanical treatment of metallic materials is described, including solidification, crystal defects, theory of solid solutions, theory of dislocations, diffusion, hardening and softening of metals and alloys.
- Syllabus of lectures:
1.Thermodynamics of systems (solutions and their free energy, heterogeneous equilibrium, Gibbs phase rule, phase mixtures).
2. Theory of solid solutions (ideal, regular and real solutions).
3.Solidification of binary systems (homogeneous and heterogeneous nucleation).
4. Microstructure and phases, crystal defects.
5. Diffusion in metals and alloys.
6. Phase transformations in solid state (martensitic and bainitic transformations, precipitation).
7. Theory of dislocations (stress and strain field of dislocations).
8. Theory of dislocations (energy of dislocations, pile-up, forces on a dislocation).
9. Theory of dislocations (dissociation of dislocations, Peierls-Nabarro stress).
10. Mechanical twinning. Interaction of dislocations with obstacles (other dislocations, solute atoms, precipitates, grain boundaries, derivation of the Hall-Petch relation).
11. Deformation hardening (monocrystals, polycrystals)
12. Static recovery, static recrystallization.
13. Dynamic recovery, dynamic recrystallization.
