Heat treatment of aluminum casting alloys
Holátko, Petr ; Roučka, Jaromír (referee) ; Kaňa, Václav (advisor)
This bechelor thesis deals with the description of the heat treatment of aluminium casting alloys and is particularly focused on the frequent heat treatment, which is hardening. The first part describes the properties of aluminium alloys and are further explained the different kinds of heat treatment. The second part describes the experiment, which were cured, two different aluminium alloys. Here, the work focuses on change in hardness before and after hardening.

Historical development of steel manufacturing processes from the Middle Ages
Závodná, Marie ; Pešek, Jakub (referee) ; Šenberger, Jaroslav (advisor)
This thesis was written during my bachelor studies of mechanical technology at the Faculty of Mechanical Engineering in Brno. The topic was processed on the basis of professional literature and accessible web servers, which deal with the linear analysis of steel production principles since the Middle Ages and with theis sues of steel reduction and oxidation processes. Contemporary modern steel fabrication procedures are based on simile principles to those which have been used fort hefabrication of steel since thediscovery of iron.

Actual trends in manufacture of permanent patterns
Benda, Tomáš ; Mikulka, Vít (referee) ; Horáček, Milan (advisor)
The aim of this bachelor thesis is to create an overview of different methods for making permanent models. According to the type of materials the models are divided into the wooden, the metallic, the plastic and the models made from the resin. Further, certain methods Rapid prototyping are described here. The thesis is completed with visual documentation.

Use of numerical simulation for reduction of scrap from Al alloys
Doležal, Petr ; Lána, Ivo (referee) ; Krutiš, Vladimír (advisor)
This thesis deals with the possibilities of current simulation software and their use in technical practice. The aim of the thesis is to describe the process of the simulation; summarise the required initial parameters of the cast in order to achieve a credible simulation, and to describe the possibilities of the use of simulation software in the area of casting defect prediction. This theoretical analysis is applied on a specific cast, which is subject to a simulation trying to find an ideal inflow system, as well as predicting the formation of possible defects. The accuracy of this simulation will be proved by analysing an actual cast product.
