Porosity dependence of sound velocities in partially sintered alumina, zirconia, ATZ, and mullite ceramic materials
Original language description
Young’s modulus and sound velocities of partially sintered alumina, zirconia,ATZ, and mullite ceramics with a broad range of porosities determined via theimpulse excitation technique (IET) and the ultrasonic wave propagation pulseechotechnique (UPT) are found to be in good agreement and exhibit sigmoidalcurves as a function of the sintering temperature. The porosity dependence ofthe relative values of Young’s modulus and sound velocities is either close to orbelow (but never above) the prediction based on an exponential relation, andnone of them is significantly below the prediction based on a percolation relationor a recently proposed numerical benchmark relation for overlappingmonosizedspheres. Values are lowerwhen concave pores or irregular anisometric grains aredominating. The correlation of the normalized longitudinal wave velocities andrelative transverse wave velocities, with VL/VT ratios ranging from 0.50 to 1.91, iswell predicted by models for Poisson’s ratios between 0.35 and 0.2.
