Propeller fan damage analysis
Vašáková, Kristýna ; Štěpánek, Roman (referee) ; Pantělejev, Libor (advisor)
This bachelor’s thesis deals with propeller fan damage analysis, which is used for air blasting of recycled glass wool. In the frame of experimental work the fractographic analysis for evaluation of damage mechanisms was performed. Further, material analysis for assessment of the material grade (chemical and metallographic analyses) was conducted. Measurement of Vickers hardness with low load was performed for determination of mechanical properties of used materials.

Microstructure of Mg alloys prepared by SLM process
Handl, Jiří ; Vašáková, Kristýna (referee) ; Nopová, Klára (advisor)
The main aim of this bachelor thesis was to research for theoretical part dealing with additive manufacturing and magnesium alloys focused on alloy AZ91D. The experimental work analyzed samples processed by Selective laser melting (SLM) technology with different process parameters. The porosity was measured on the individual samples and the microstructure of alloy AZ91D processed by SLM method was described. The results were linked to the process parameters used and, also to the available literature.

Microstructure of AlSi9Cu3 alluminium alloy processed by SLM technology
Rychnovský, Daniel ; Nopová, Klára (referee) ; Vašáková, Kristýna (advisor)
This bachelor thesis deals with microstructure of aluminium alloy AlSi9Cu3 produce by SLM process. In theoretical part the SLM process is shown. In following topic, the defects which can occur during SLM are mentioned. In the end of the theoretical part the materials made by SLM and materials made by conventional method (casting) are compared. In experimental part the porosity of the samples made by SLM is examined by image analysis. The examine of the microstructure is also included. Results are discussed with literature.

Mechanical properties of materials prepared by SLM process
Vašáková, Kristýna ; Řehořek, Lukáš (referee) ; Pantělejev, Libor (advisor)
This diploma thesis deals with properties of multi-materials interface composed of pure iron and Cu7Ni2Si1Cr alloy produced by SLM process. The theoretical part of thesis is focused on selective laser melting technology, and on description of defects connected with the production of SLM parts. Furthermore, one section deals with the production of multi-materials prepared by the SLM process. The experimental part of this thesis deals with selections of the SLM process parameters appropriate for bulk samples preparation. Mechanical properties were determined by the tensile tests at room temperature. Metallographic and fractographic analyses were performed for evaluation of the microstructure and description of the fracture mechanisms.
