Abstract (EN)
This thesis involves the production of the compound (Ta0.75Al0.25B2) in the TaAl-B ternary system in powder and bulk forms. Ta0.75Al0.25B2was synthesized in powder form by mechanical alloy-assisted heat treatment in a high-energy Spex mill at 1500 °C. The obtained powder was sintered under 45 MPa pressure at 1300 - 1600 °C using the Spark Plasma Sintering method. Phase content (XRD), microstructure (SEM), chemical composition (EDS), behavior under temperature (DSC-TG), physical and mechanical properties were analyzed. The sample obtained by the SPS method achieved a relative density of 98.6% and a hardness of 24.41 GPa. Keywords: MAB Phases, Mechanical Alloying, Spark Plasma Sintering, Ta-Al-B, Ta0.75Al0.25B2, Hardness
