摘要
A kinetic study of the aging behavior of tetragonal zirconia polycrystals (TZPs) from 100° to 500°C suggests that there exists a cricital grain size of 0.52 μm below which the tetragonal symmetry can be retained. Property degradation of TZPs at low temperatures is connected with transformation‐induced microcracking. It is reported here that the temperature range of 100° to 400°C in which degradation occurs could be explained by an infinite incubation time for the lower limit and by the martensite starting temperature for the upper limit.
