Structural Stability of Creep-Resistant Steels and their Weldmets
Šohaj, Pavel ; Jan, Vít (referee) ; Foret, Rudolf (advisor)
The structural stability of creep-resistant steels P22, P91 and Eurofer´97 and structural stability of weld joint P22/P91 have been studied. The microstructural changes during annealing at temperatures of 500 – 900°C were examined. The state of equilibrium have been simulated using the ThermoCalc software. The computed results were compared with published data. A good agreement between the simulation and the published data was observed.

Verification of heat treatment on properties of progresive heat resisting steels
Volf, Ondřej ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
The topic of this thesis is pre-welding process specification for heat reisisting T24 steel with TIG method. This is concerned welding waterwalls during construction electrical steam boilers. The main advantage T24 steel, except high heat resistance, is T24 doesn´t need to pre-heating neither post-welding heat treatment. Two tubes from T24 steel was flash welding and evaluating weld metal with several tests in this experiment. ALSTOM Power, s.r.o is submitter of this project.

Materials used in Aerospace Industry
Večeřa, Jiří ; Juliš, Martin (referee) ; Hutařová, Simona (advisor)
This bachelor’s thesis deals with contemporary aerospace materials. First part of this thesis is engaged in aircraft construction. There is description of the most important components of fuselage and jet engine, its function, various types and materials, which is used to its production. Other part is engaged in these materials. There are aluminum alloys, titanium base alloys, nickel and cobalt base superalloys, heat-resisting steels and composites.
