FACTORS AFFECTING THERMAL SHOCK RESISTANCE OF POLYPHASE CERAMIC BODIES
CARBORUNDUM CO NIAGARA FALLS N Y
Pagination or Media Count:
An investigation of the factors which effect the thermal shock resistance of polyphase ceramic systems was conducted with the model system zirconium carbide-graphite. The research was divided into two areas 1 theoretical calculations of the individual material properties, which show that the included graphite particles may be regarded as spherical pores and 2 experimental data, which substantiate the postulate that increased thermal shock resistance is a result of an increase in the ratio of strength over Youngs modulus, brought about by the addition of the low Youngs modulus phase.
