Abstract

The process of formation of solid solutions of the (Ti, Zr, Hf)B₂, (Zr, Hf, Nb)B₂ and (Zr, Hf, Ta)B₂ composition was carried out. The heterophase microstructure is formed in this system, consisting of a solid solution and inclusions based on HfB₂ and TaB₂. It is shown that increasing the densification temperature it is possible to increase diffusion processes and, as a result, increase the elements solubility. The highest solubility was observed in the case of arc melting, when all components were in a liquid phase. However, for the (Zr, Hf, Ta)B₂ composition, the TaB₂ individual inclusions are formed. This is due to the fact that the energy of TaB₂ formation significantly differs from the energy of other components.
