Acoustic Microscope Study of a Titanium Diffusion Bond
The need for more reliable and cost-effective nondestructive inspection methods is never ending. In particular, the ability to locate and possibly to quantify the microscopic strength-determining imperfections in diffusion bonds suggests that ultra-high frequency (UHF) ultrasonic techniques might render an appropriate tool. However, the investigation of diagnostic techniques of diffusion bonds via the acoustic microscope with micron dimensional resolution capability has been surprizingly sparse1. In addition, the metrology mode2 of this versatile inspection tool has to date not been invoked in this context to ascertain the elastic properties in the immediate vicinity of the joined surfaces of a diffusion bond.
