Description

In recent years, the process of diffusion bonding has found considerable usage in the aerospace and nuclear power industries [1]. This process entails two surfaces being pressed together at elevated temperatures and high pressures. If ideal conditions are achieved, the bonded interface will have properties identical to those of the matrix metal and the microstructure will be continuous across the interface. There is a fine margin for error in attaining ideal conditions and the ability to characterize the bond nondestructively is highly desirable. The present project is aimed at the development of ultrasonic techniques for the characterization of interfaces between two joined parts. The techniques that are being used have applicability to components joined by diffusion bonding, pinch welding, and friction bonding, and may also be useful in nondestructive measurements of rubbing friction and for bond strength.
