Description

In recent years, new methods of bonding solids have been introduced. These methods (e.g., diffusion bonding and pressure welding) can produce very high quality bonds. In favorable cases the strength of the material in the bond is nearly indistinguishable from that of the host. Similarly, metallographic analysis may indicate almost no microstructural change between the host material and the material in the bonding region. Since these bonds can be of such high quality, they are being used for critical joins. Consequently, an urgent need has arisen for reliable nondestructive inspection methods. This paper is concerned with the use of ultrasound to determine bond quality [1–5].

Ultrasonic Characterization of Solid-Solid Bonds from Microstructural Changes
