High-temperature creep of refractory ceramics. Kinetics and the effect of experimental conditions

High-temperature creep curves of samples of refractory ceramics are considered. It is shown that in the vast majority of cases strain in samples accumulates linearly. Regularities of creep flow rate change under the effect of temperature and loads are established. The sample structure is shown to affect the creep kinetics.Translated from Ogneupory, No. 6, pp. 2–8, June, 1994.
