In this study boron nitride‐containing composites (BNCC) with high strength, low Young's modulus and highly improved strain tolerance have been developed by reaction synthesis technology. The in situ formed BN particles with fine (nanosized) particle size were distributed homogeneously and isotropically in the matrixes, which decreased the negative effect of the BN phase on the composite properties. In order to be relevant to the wide applications in the steel industry such as break rings for horizontal casting of steel, the BNCC (i.e., AlON–BN composites) were evaluated in terms of the corrosion resistance to molten steel, wear and thermal shock resistance. The results demonstrate that the AlON–BN composites outperform those of the currently employed materials especially with respect to corrosion resistance.
