Prediction of Service Life of Cordierite-Mullite Refractory Materials by Non-Destructive Methods

Investigation the effect of sintering temperature on Young’s modulus evaluation and thermal shock behavior of a cordierite–mullite based composite

“…Since the formation of the cracks has a profound influence on the ultrasonic velocity and the Young's modulus of the material, measuring either of these properties may be applied to monitor the development of the thermal shock damage level [12][13][14]. There were many reports about the practical application of ultrasonic pulse velocity test (UPVT) to characterize and monitor the properties of industrial refractory [4,[15][16][17].…”

“…The non-destructive method such as the ultrasonic pulse echography has the great advantages for monitoring of damages and Young's modulus values for evaluation of thermal shock resistance of materials [11][12][13].…”

“…In recent years, ultrasonic pulse echography methods have been used to evaluate the Young's modulus, a material property which is depended on the intrinsic elastic properties of constituents, and also related to the damage of material [4,13].…”

Determination of thermal shock resistance of silicon carbide/cordierite composite material using nondestructive test methods

“…Various publications have dealt with the practical application of UPVT to characterize and monitor the properties of industrial refractory materials nondestructively. [3][4][5][6][7][8][9][10][11][12][13][14] The UPVT method has been considered in detail in Ref. 2 Briefly, pulses of longitudinal elastic stress waves are generated by an electro-acoustical transducer that is held in direct contact with the surface of the refractory under test.…”

“…By determining the bulk density, the Poisson's ratio and ultrasonic velocity of a refractory material it is possible to calculate the dynamic modulus of elasticity using the equation below 3,[8][9][10][11][12][13][14] :…”
