Production of castings from Cu-Ni based alloys
Kelbl, Michal ; Kaňa, Václav (referee) ; Záděra, Antonín (advisor)
This master thesis is focused on melting of Cu-Ni based alloys and production of castings from these alloys. The theoretical part includes introduction of Cu-Ni based alloys and their properties and application. At the end of this part is production foundry technology of Cu-Ni alloys described. In the practical part two proposed melt controls for cupronickel (Cu-Ni) and for monel (Ni-Cu) have been performed. From these melts trial castings, castings of blades and bearings have been produced. The trial casting and the casting of bearing have been produced by using sand moulds and the casting of blade by using ceramic shell. According to internall quality of produced castings the performed melt controls have been evaluated. In addition to the internal quality of the castings, the chemical composition, microstructure and mechanical properties were evaluated.

Hydraulics forceps for heavy manipulators: compare of design welding or casting constrution
Burian, Viktor ; Šubrt, Kamil (referee) ; Knoflíček, Radek (advisor)
This bachelor´s thesis discusses forging manipulators and their use in free forging. It describes principle of functionality and structure of these machines, which serves as a special accessory for forming machines. It describes the construction technology of casting and welding structures. It executes proposal of casting and welding construction pincers for selected load capacity and the basic design calculations are made according to this proposal. Then, these structures are evaluated in technical and economical view.

Castings from TiAl alloys for the turbochargers
Kudýn, David ; Malec, Silvestr (referee) ; Zemčík, Ladislav (advisor)
The bachelor thesis is focused on the analysis of intermetallic alloys TiAl. First of all, it is analysed their properties and the way how they change depends on their treatment and influencing of alloying elements. Then ways of utilization in practice are stated here. Attention is concentrated especially on turbochargers wheel and their comparison to convention materials. After that individual options of melting and casting and materials for melting crucibles and moulds associated with them are there discussed. In the end, the thesis has analysed the ways of recycling of residual material.
