Subject syllabus:

Lectures: 1. Importance of heat treatments; basic classification – heat treatment, thermo-chemical treatment; thermo-mechanical treatment; equilibrium vs. non-equilibrium heat treatments. 2. Iron – carbon system, austenite phase transformations upon cooling; diffusion, diffusion less transformations – products – ferrite, pearlite, bainite, martensite. 3. Diagrams of isothermal and non-isothermal austenite decomposition upon cooling – principle, construction, use. 4. Non-desirable processes during heat treatments – decarburizing, oxidation. 5. Classification of steel annealing; stress relief annealing, recrystallisation annealing, spheroidising annealing; thermal cycles of annealing, final structure and properties. 6. Normalising; homogenising annealing; thermal cycles of annealing, final structure and properties. 7.-8. Steel quenching; quenching media; hardenability and its testing; methods of cooling – modified quenching procedures. 9. Tempering of steels – tempering stages, impact on the steel properties. 10. Internal stresses as a result of the heat treatment – thermal stresses, structure stresses. 11. Thermo-chemical heat treatments; basic principles; case hardening – principal reactions, technologies, quenching and tempering after carburising, resulting properties. Nitriding and carbonitriding; principles, technologies, resulting properties. 12. Heat treatments of the cast irons; classification of the cast irons; heat treatment of grey and nodular cast irons; malleablising of the cast irons. 13. Heat treatment of some non-ferrous metals (aluminium, copper and their alloys); principle and stages of precipitation hardening; ageing. Summary; importance of the heat treatment of metallic materials.
