Abstract
- Production of single-phase carbide high entropy ceramic (Hf0.2Ta0.2Ti0.2Nb0.2Mo0.2 or Zr0.2,)C by self-propagating high-temperature synthesis (SHS) from a mechanically activated (MA) reaction mixtures and mechanical synthesized (MS) materials is discussed. The influence of mechanical treatment time at ball mill, on the formation of the phase of a high-entropy material is investigated. Spark plasma sintering and their structure, phase composition, obtained bulk samples and mechanical properties were studied. A self-propagating high-temperature synthesis of high-entropic carbide based on refractory elements was also carried out. The microstructure and mechanical properties of high-entropy ceramics obtained by the methods of mechanical synthesis and SHS were compared.
