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.
Toughness of Metallic Materials and its Testing
Michalisko, Jan ; Zapletal, Josef (referee) ; Němec, Karel (advisor)
This bachelor work deals with toughness as a mechanical property of metal materials. It defines the toughness and its demonstrations. It describes the transient behaviour of some metals at the static and dynamic load. Furthermore, the work describes the particular testing methods (Charpy‘s, Izod‘s, DWT, DT, DWTT). It covers the historical consequences of toughness testing.
