Strength and Creep of Special Ceramic Bodies in Tension at Elevated Temperatures
NATIONAL BUREAU OF STANDARDS GAITHERSBURG MD
Pagination or Media Count:
Investigation was made to determine the behavior of ceramic bodies in tension at high temperatures. Observations were made on six ceramic bodies covering the determination of their tensile strength and creep during prolonged stresses ranging from 3000 to 15000 psi and at temperatures ranging from 1500 to 2230 deg F. Rending tests at 1800 deg F gave modulus of rupture values for commercial specimens which ranges from 4900 to 18000 psi while the values of the bodies developed at the Bureau of Standards ranged from 6000 to 38000 psi. Creep was not measurable.
