N2 - The machining damage and porous flaws in silicon nitride were studied to determine what factors affected the changes in the Weibull parameters at 25 °C and 850 °C. The experiments were performed using a diesel exhaust valve. Censoring showed that the Weibull strength distributions representing each flaw changed as a function of dynamic fatigue and temperature. Because the surface area and volume of the valve were observed to be larger than the tested bend bars, the failure probability analysis amplified some distribution changes which were not evident from the interpretation of the censored bend bar strength data.
