碩士 === 國立中央大學 === 機械工程學系 === 84 === Degradation in mechanical properties of a polycrystalline
alumina subjected to thermal shock loading was studied via
residual flexure strength measurement and several
nondestructive evaluation methods.
Experimental results of two specimen sizes can be well explained
by the thermal elastic and fracture energy theories. In
the cyclic thermal shock testing with the quenching
temperature difference below the critical temperature
difference, no significant thermal fatigue damage was observed
as indicated by the results of residual flexure strength
measurement and other nondestructive evaluation methods
such as dye penetration, ultrasonic and strain gage
measurement of elastic modulus, and Vickers indentation har
dness and crack growth observation. The evaluation of the
applied nondestrucyive evaluation methods as a
detecting tool for thermal shock damage is conducted by
comparing with the results of residual flexure
strength measurement.
