Properties and the Use of Metal Foams
 Křivánek, Robin ; Liškutín, Petr (referee) ; Němec, Karel (advisor)
In this thesis are summarized the findings of metal foams, with prevailing constraints on aluminum foam, because in them hides the greatest potential. The first part is described the production of porous materials, especially the way of floam production by thermal decomposition of floaming agent and melt gas injection. There are also written stress tests to gain a deeper knowledge of their properties, but also the latest exploring methods of foams, such as using a radioscopiy and CT scanner from which then creates a voxel model of foam. They are summarized here the basic ways of processing. Finally we must mention the possibility of using these materials with a focus on commercially produced foams Alporas® and Duocel®. Mass using foams mainly prevents high production costs and in some cases difficult reproducibility of properties.

Manufacture of heavy castings - manufacturing technology
 Návrat, Radim ; Glos, Jaroslav (referee) ; Záděra, Antonín (advisor)
This bachelor’s thesis deals with the problems in the production of heavy castings and tries to explain the main aspects of this manufacture. Work is therefore focused on differences between manufacture of heavy and usual castings.
