The aim of this thesis is preparation and characterization of bulk magnesium-titanium based materials. In the first theoretical part properties of based materials and complexity of preparation alloy from these metals is discussed. Second part is focused on powder mattalurgy and its applicability on Mg-Ti based system. In another part particle composition are described. The experimental part of this thesis was the preparation of blk Mg-Ti based materials from metal powders. For sample preparation conventional methods of powder metallurgy and spark plasma sintering wa employed. Furthermore a characterization of these materials was done. Microstructure was observed. Present phases were found using X-raf diffraction analysis. Amounts of these phasees were determined using a scanning electron microscope with energy-dispersive spectrometry and using X-ray fluorescence. Further more hardness was measured and bending test with evaluation was done. Significant difference in results of samople preparation using conventional methods aof powder metallurgy and spark plasma sintering was observed.
