Synopsis:

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.

Requirements:

Physics of Metals 1

Physics of Metals 2

Physical Metallurgy 1

Syllabus of lectures:

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.

Syllabus of tutorials:

Laboratory excercises: Activation volume and instrumented Charpy impact test. Written record from laboratory excercises is required.

Study Objective:

Knowledge:
