摘要：

Features of ultrasonic testing of aluminum single crystals are discussed. Ultrasonic waves were generated by PZTs, and acoustic fields on the opposite surfaces of single crystals were analyzed using a laser interferometer. Flaws opening on surfaces were detected in single crystals grown along the [001] axis. Features of elastic strain fields due to waves propagating along the [111] axis have been studied.
