Conclusions

The introduction of 0.2- to 6-μm carbon particles into zirconium carbide leads to a nonmonotonic variation of the strength, fracture toughness, and thermal fatigue resistance of the resultant zirconium carbide-carbon composites as functions of free carbon content, with maxima at about 2.5 wt. %. Coarser (50-μm) carbon particles added in larger quantities have a deleterious effect on the strength properties. The addition of a carbon component to zirconium carbide can, depending on the nature of the former, both increase (synthetic diamond and PGI graphite) and decrease (KLZ graphite) the thermal fatigue resistance of the resultant composite.
