	Fracture behaviour of heat affected zone near heterogeneous weld joint Jelínek, Vladimír ; Válka, Libor (referee) ; Juliš, Martin (advisor) The study deals with mechanical characteristic of heterogeneous weld joint. The low carbon steel 22K and austenitic steel have been used as a experimetnal materials. The low carbon steel has special properties in basic condition. The sample has been evaluated in basic condition and after annealation. There have been evaluated impact of annealation proces to structure and mechanical charakteristics in experimental part of study. The particularised analysis of microstructure has been done by pictorial analysis. Mechanical characteristics has been examinated in both conditions by 2 different methods – measurment of microhardness according to Vickers and test of fracture toughness on compact tension specimens.

	Mechanical properties and fracture behaviour of welded joints and base materials in water turbine supply piping Vlk, Václav ; Šiška, Filip (referee) ; Válka, Libor (advisor) The master thesis is focussed on evaluation of mechanical properties and fracture behaviour of basic materials and weld joints of a water turbine supply pipe. The results of tensile tests, fracture toughness tests, hardness and micro-hardness tests and further chemical and metallography analysis are used for operating degradation level evaluation of the construction material and also for a residual operating recognition of the second, identical specimen of supply pipe.
