A new method for estimation of elastic properties of sintered iron powder compacts from ultrasonic longitudinal
Abstract:
A new methodology has been proposed for estimation of elastic moduli of iron powder compacts solely based on longitudinal ultrasonic velocity. New correlations have been semianalytically derived between the elastic moduli and the longitudinal ultrasonic velocity. The moduli estimated on the basis of the suggested methodology agreed reasonably well with data reported for iron powder compacts in the literature. The proposed method can be a potent tool for quick and accurate, nondestructive estimation of elastic properties for porous materials through ultrasonic measurements.
