An investigation was conducted to determine the bonding phenomenon in cermets after exposure at temperatures above the melting temperature of the metal. The experiments conducted with boron carbide and each of three metals showed that nickel, cobalt, and iron formed a bonding zone between the metal and the ceramic. The elevated temperature properties of a boron carbide cermet containing iron were investigated in the temperature range of 1600° to 2600°F. The properties evaluated were room‐ and elevated‐temperature modulus of rupture, resistance to fracture by thermal shock, oxidation characteristics, and density. These properties were compared with those of hot‐pressed boron carbide.
