Properties of quasicrystal-reinforced high entropy alloys
 Adami, Martin ; Tesař,, Tomáš (referee) ; Čížek, Jan (advisor)
This diploma thesis deals with the processing of the high-entropy alloys with the addition of quasicrystals by the spark plasma sintering method. The aim of this thesis is to evaluate the influence of quasicrystals content on the microstructure and wear resistance. The literature review part is divided into several section. The first part is an overview of high-entropy alloys and quasicrystals, including their properties and production methods. The next part pertains to spark plasma sintering and the wear phenomenon. In the experimental part, spark plasma sintering compacts were produced at 1100 °C and an analysis was performed using scanning electron microscope as well as X-ray diffraction and their tribological properties were measured by the pin-on-disc method. It was found that increasing the content of quasicrystals triggered an improvement in the compacts’ wear resistance.
