The course is based on previously acquired general physical and physical metallurgical knowledge and applies this knowledge to real systems such as Fe-C and Fe-X-C, multicomponent Fe and Ni -based alloys, etc., which are the basis of steels and special structural materials. Since the Physical Metallurgy 2 builds on the previous, more theoretically oriented courses of Metal Physics and Physical Metallurgy 1, added emphasis is placed on applications of real systems in engineering.
1. Recapitulation of basic principles. Overview of experimental methods. 2. Equilibrium diagram Fe-C - metastable and stable systems. 3. Phase transformation in steels in general - kinetics of transformation and its measurements. 4. Austenite decomposition - TTT diagrams. 5. Diffusional transformation (nucleation and growth), pearlite and bainite transformations. 6. Diffusionless martensite transformation (shear, twinning). 7. Tempering of martensite. Formation of carbides (epsilon-carbide, cementite, complex carbides metastable and stable). 8. Recovery and recrystallization. 9. Physical principles of the heat treatment. Quenching, hardening, annealing, tempering, etc. 10. Thermal - mechanical treatment. 11. Surface treatments and their physical basis. Surface hardening, carburizing, nitriding. 12. Structural steel - an overview. 13. Special steels (corrosion-, creep-, heat-resistant, tool steels, etc.).14. Special alloys - an overview. Notes to present research trends.
