Thermodynamics of interaction between refractory compounds and metal melts

  • Published:
Powder Metallurgy and Metal Ceramics Aims and scope

Based on the thermodynamic assessment of equilibria in “refractory compound–metal melt” systems, the interaction in B4C–Al (Ni, Ni–Si, Ni–Mo) systems is predicted within the Van Laar theory at temperatures to 1800 K. It is established that interphase-active elements (nickel, titanium, vanadium, and chromium), being in a solid-solution state, do not show sufficient chemical activity or do not form new chemical compounds in interaction with refractory compounds (carbides, borides, and nitrides of IV–V group metals) unlike “refractory compound–liquid metal (Ni, Cr, Ti)” systems.
