Highlights: [•] Cr3C2 is a useful transient liquid phase sintering agent for carbide-based ceramics. [•] Low atomic mass cations (e.g., Cr or Ti) can rapidly diffuse through oxide scales. [•] Minor second phase additions can promote limited liquid formation for pore filling. [•] Oxycarbide interlayer may comprise nanocrystalline graphite in amorphous oxide. [ABSTRACT FROM AUTHOR]
