The compressive yield stress and bending strength of NiAl–CrB2 composites are studied in the 20–800°C temperature range. The effect of the composite phase ratio and experimental temperature on the composite strength for different loading patterns is established. During tensile stresses, the introduction of 15 wt.% CrB2 into the intermetallic is optimal to ensure the maximum bending strength of the composite at 500°C. The bending strength of NiAl–15 wt.% CrB2 composite at the experimental temperature 500°C exceeds that of the starting NiAl, by a factor of 3.
