Abstract: The relationship of applied stress fracture time-fracture propability of sintered Si3N4 was investigated. The experimental results show that the weibull modulus m obtained by bending strength distribution can not describe accurately the delayed fracture distribution of sintered Si3N4.The modified STP diagram was obtained with consideration of delayed fracture distribution by means of iterative regression analysis.
