Abstract

The ultrasonic backscattering characteristics were measured for IN-100, a powder metallurgy alloy used for engine disk components. The data were obtained with a variety of different transducers placed either in a waterbath or in sample contact for a frequency range from about 2 to 18 MHz and statistically averaged over numerous volume elements of the samples. Micrographical examination provided size and number distributions for grain and pore structure and showed that the predominant source for backscatter were the larger micropores. Two samples with different micropore densities were used to demonstrate the feasibility of calculating microstructural parameters from the ultrasonic data.
