 note = {The ultrasonic measurement was carried out to detect porosities in aluminum alloy base composite castings (MMC-Casts) produced by hybrid method of the sand-mold casting and the low pressure casting. Irradiation of the ultrasonic wave with a frequency of 5 MHz and 20 MHz showed that the ultrasonic wave propagated to the bottom of the specimen of 10 mm in thickness with large scatter from SiC particles distributed in MMC-Casts. By using the Al-Cu alloy castings with a thickness of 19 mm, artificial holes of different diameter were measured from the other side, and a hole of 1 mm in diameter was detected with the
ultrasonic wave of a frequency of 5 MHz., text, application/pdf},
