The resistance of several polycrystalline TiB 2 materials to penetration by liquid aluminum at 970°C was investigated, and their microstructures were characterized. The grain‐boundary properties of individual diborides rather than the intrinsic properties of TiB 2 are thought to control stress corrosion susceptibility in liquid metal environments.
