Production and properties of hot-pressed materials based on silicon carbide with additions of boron and titanium carbides

Resumo

Special features of pressure sintering materials based on silicon carbide with additives of boron and titanium carbides have been investigated. The kinetic parameters of the densification have been established. Special features of the structure and physico-mechanical properties of hot-pressed materials of the SiC(8–20 wt %)–(B₄C–TiC) system have been studied. Dense materials have been produced based on si-licon carbide with increased (3.8 MPa•m^1/2) fracture toughness and low (0.07 Ω•m) electrical resistance.
