Review of Progress in Quantitative Nondestructive Evaluation

In recent years, the process of diffusion bonding has found considerable usage in both the nuclear power and aerospace industries. This process requires the compression of mating surfaces at an elevated temperature for a given time. If optimum conditions of time, temperature, pressure and surface cleanliness are achieved, diffusion of material across the interface will occur, yielding interfacial mechanical properties identical to those of the bulk material. The use of insufficient bonding conditions may result in void formation, precipitation of undesired phases or lack of grain growth across the interface. The consequence will be an interface that is less than ...

Review of Progress in Quantitative Nondestructive Evaluation

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 ...

Review of Progress in Quantitative Nondestructive Evaluation

Detection of flaws is an important industrial concern. For example, aircraft and nuclear-power reactor owners and regulatory authorities need effective means of detecting flaws that could pose a threat to public safety. Operators of costly equipment require information on service-induced flaws to be able to make run-or-retire decisions. As the cost of parts and concerns for public safety increase, the importance of flaw detection and size estimation has likewise escalated.
