Diagnosis of the fire damaged bridge
 Olejková, Sabina ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
This thesis is about assessment of a bridge construction influenced by fire accident. The bridge is situated at the highway D46 beyond the town Držovice. Within this construction research, there will be mentioned diagnostic methods – A non- destructive method (Ultrasonic pulse method and hardness tests) and destructive methods (borehole and tear off tests). For find out in which way was the concrete of the bridge damaged and hurt while facing a high temperature of fire, there were taken samples, which were analyzed by physical and chemical test. We can analyze composition and microstructure of the concrete. The result of this tests will be evaluated, and the actions of a remediation will be suggested.

Mechanical properties of the weld of titanium alloy TiAl6V4 prepared by using an electron beam technology
 Byrtus, Robin ; Pantělejev, Libor (referee) ; Válka, Libor (advisor)
The aim of the diploma thesis is to evaluate the mechanical properties and fracture behavior of the weld join Ti6Al4V titanium alloy prepared by using an electron beam technology. The theoretical part deals with the welding of titanium alloys with the help of electron beam, the weldability evaluation of titanium alloys, the influence of electron beam welding on the microstructure and the methods of testing of weld joints. Using the experiments, the mechanical properties of the base material and the weld were evaluated and a structural analysis of the weld was performed.
