The use of aluminium parts in construction of ingeneering constructions
Suk, Pavel ; Střítecký, František (referee) ; Roučka, Jaromír (advisor)
Study describes is dealing with the application of the aluminum extrusions for industrial purposes. The introduction is dealing with the industrial applications in general terms. It includes the chemical and physical properties of aluminum. It is followed by description of various aluminum alloys, their properties such as suitability for machining, welding, plasticity and resistance to corrosion. Next chapter is listing aluminum applications, namely as a building components in civil engineering such as various extrusions and a modular components. At the closing of this paper there is an example of an actual application of aluminum prefabricated conveyer segments. The conveyor is part of an assembly line for K350 units.

Controled crystallisation of aluminium alloys castings poured in shell moulds
Mašková, Lenka ; Střítecký, František (referee) ; Roučka, Jaromír (advisor)
The aim of this thesis is to verify a possibility of controlling the crystallisation of aluminium alloys poured in shell moulds in order to achieve directional solidification. For this purpose, new cooling plant has been designed and fabricated. Several sample castings were produced under different initial conditions. Based on the evaluation of measured temperatures, a numerical simulation of heat transfer was created using the ProCAST software. Finally, the sample castings were sectioned into specimens that were, subsequently, metallographically polished and the evaluation of their structure with respect to the amount and types of defects was performed.
