Abstract

This paper reports a new method of estimating ultrasonic properties of sintered materials from the ultrasonic properties of its powder compacts. The methodology is based on the observation that the ratio of ultrasonic shear wave velocity to longitudinal wave velocity is a function of porosity only and varies linearly with longitudinal velocity. The efficacy of the proposed method has been established with experimental data obtained from previously published studies. The method can be used as a potential tool for quality control of sintered products.
