Využití litinových materiálů v konstrukci dopravní a manipulační techniky
HAKLOVÁ, Lenka
The content of this research work is devoted as comprehensively as possible to the issue of basic types of cast irons, from their origin as one of the iron alloys, to their characteristics, properties and use as a construction material in the field of transport and handling technology. The work is supplemented by information about iron as a chemical element, iron ores, metals, crystallographic systems and, last, but not least, a diagram of iron - carbon, which is directly related to cast iron
Statistics of directional data with an application in crystallography
Karafiátová, Iva ; Šedivý, Ondřej (advisor) ; Hlubinka, Daniel (referee)
The main purpose of this thesis is to derive methods used to estimate the mean orientation of a grain in polycrystalline material. The estimation is highly impor- tant in crystallography. However, it is often expressed by only one representative value regardless of its variability within the grain. In this thesis we present the basic concepts of crystallography, including the principle of the Electron Backs- catter Diffraction, which is used to explore the microstructure of a polycrystalline materials. Subsequently, we present six of the most commonly used descriptors of three-dimensional orientation of a crystal lattice. This overview is completed by the summary of the particular relationships between those descriptors. In the practical part of this thesis we apply derived methods on real data within the scope of research of microstructure of an aluminum alloy. 1
