Title: Utilization of field-assisted sintering technique for fabrication of metastable beta titanium alloy in a rod shape Author: Adrián Majoros Department: Department of Physics of Materials Supervisor: RNDr. Anna Veverková, Department of Physics of Materials Abstract: We worked with a metastable β titanium alloy Ti-15Mo in the form of a rod produced by field-assisted sintering method (FAST) in this bachelor's thesis. The samples were subjected to classical methods of thermomechanical processing, namely forging and solution treatment. We have investigated the effect of the alloy processing on its microstructure and mechanical properties and compared them with an alloy produced commercially. The characterization was performed by scanning electron microscopy, Vickers microhardness measurement, Archimedes method of porosity measurement and tensile testing. Using Archimedes method, we obtained a quantitative description of porosity of produced rods, which was further qualitatively confirmed by microstructure analysis using scanning electron microscopy. We have found out that in order to achieve a microstructure similar to the microstructure of a commercially produced rod, it is necessary to subject the sintered rod to further processing particularly to forging. After solution treatment, the forged sintered rod...
