| Summary |
|---|
| Subject is aimed at theoretical and also practical knowledge from the field of properties, production and/or treatment of progressive materials types on iron basis and their direct control in manufacturing process with aim to obtain products with optimised properties. Analysis of phase transformations in details and their utilisation in manufacturing process is an integral part. |
| Learning Outcomes of the Course Unit |
|---|
- student will be able to classify various steel types, including their applications
- student will be able to suggest suitable treatment in frame of direct control of austenite transformation products for optimised final steel properties
- student will be able to choose the optimal material type on the iron basis for concrete application |
| Course Contents |

1. Austenite transformation products (reconstructive and displacive transformation), their physical-metallurgical conditions of formation and mutual relations – their directed control and possible applications – part .1
2. Austenite transformation products (reconstructive and displacive transformation), their physical-metallurgical conditions of formation and mutual relations – their directed control and possible applications – part 2.
3. Granular bainite – its physical metallurgical core. Granular bainite impact on fracture response and possibilities of direct control for its occurrence restriction.
4. Automotive industry steels, their chemical constitutions, properties, potential processing and/or treatments, including their direct control (LC, IF, IF-HS, HSLA, Rephos, BH, DP, TRIP, martensite steels) – part 1.
5. Automotive industry steels, their chemical constitutions, properties, potential processing and/or treatments, including their direct control (LC, IF, IF-HS, HSLA, Rephos, BH, DP, TRIP, martensite steels – part 2.
6. High manganese steels – Hadfield´s steel, chemical composition, heat treatment, properties and technical application.
7. High manganese steels of TWIP and TRIPLEX types – their chemical compositions, processing conditions, properties, heat treatments and possible applications.
8. Spring materials on the basis of iron with different application demands and their heat treatments.
9. Maraging steels, their chemical composition, processing principles including heat treatment and/or thermo-mechanical treatment. Utilization in technical praxis.
10. Ferritic and austenitic anticorrosion steels – properties, processing principles and analysis of possible negative features, including ways how these prevent, resp. these eliminate. Utilization in technical praxis.
11. Duplex, martensitic and dispersively strengthened anticorrosion steels - properties, processing principles and analysis of possible negative features, including ways how these prevent, resp. these eliminate. Utilization in technical praxis.
12. Heat and fire resistant steel – chemical composition influence on steels properties, selected creep steels (T22, P23, P24, P91, P92) and their basic features. Carbide phases types, including crystallography structures, nucleation positions and their influence on creep resistance.
13. Influence of precipitation strengthening, including phases of Laves, of secondary hardening, influence of thermal embrittlement and the Z-phase on the creep response.
14. Explosively welded materials and their technical application, steels for pressure bottle production. |
