An ultrasonic method is used to assess the thickness of a binary diffusion zone. The theoretical analysis of the interaction of an acoustic wave with the diffusion zone shows that the amplitude and the phase of a reflected ultrasonic signal can be used to deduce information on the diffusion zone. In order to verify this prediction experimentally the authors have chosen to investigate the interaction of ultrasonic waves with the interface in Al-Cu diffusion couples. According to the phase diagram of this system several intermetallic phases are formed at the interface of the diffusion couple. Satisfactory agreement was observed between ultrasonic and direct measurements of the diffusion zone thickness.
