Tensile, creep, and modulus of elasticity data were determined for hot‐pressed zirconium carbide. The material was relatively impure, containing 1 to 2% nitrogen and 1 to 2% free carbon. Tension and creep properties, which were measured to 2600° C, indicated that above 2100°C the strength was 2000 psi or lower and the elongation was 40% or more, thus signifying little structural usefulness. It is proposed that the results were influenced by impurities at the grain boundaries. Room‐temperature modulus of elasticity values averaging 51.6 × 10 6 psi were obtained by dynamic methods.
