摘要：
The effects of water entry postures on thermal shock behavior during quench tests were investigated for the first time using alumina ceramic. The differences in the crack patterns and residual strength for specimens with different water entry postures after the quench tests were shown. At the initial thermal shock temperature of 310 degrees C, the average residual strength of the lateral posture specimens is 330.4MPa, but the longitudinal ones' is 118.4MPa. The results showed that water entry posture strongly affects the quenching thermal shock behavior; to better experimentally characterize the thermal shock resistance, the unified water entry posture during testing must be considered.
