The Pulse discharge welding applications and weld analysis
Kocák, Tibor ; Molliková, Eva (referee) ; Jan, Vít (advisor)
Theoretical part of this bachelor's thesis contains overview information about special welding technology, which uses capacitor discharging. Pracitcal part is about experimental attempts showing the application of the theory of welding using capacitor welder with specific settings, preparation and rating samples. Microstructure of the samples was evaluated by standard metallographic techniques.
The Influence of Heat Treatment on the Structure and Mechanical Properties of Tool Steels
Tobolík, Stanislav ; Němec, Karel (referee) ; Molliková, Eva (advisor)
This bachelor thesis deals with the properties of tool steels after heat treatment. The theoretical part describes the properties of iron and its alloys with carbon, and an overview of the use of steel. It is also discussed in detail the heat treatment of tool steels and manufacturing process analysis and metallographic sample. In the last part of the bachelor thesis there are described the mechanical testing of metals. In the practical part it is tested structure and mechanical properties of the selected tool steels for two types of heat treatment and the results are compared with the requirements imposed on it.
