Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.
This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract
The detection of defects that are located deep in thick walled ( >12 mm ) aluminum plates is of interest to both the aircraft and space industries. Conventional eddy current (EC) techniques are limited to the inspection of surface and subsurface anomalies. Newly developed high sensitivity magnetic sensors, such as magnetoresistive elements and superconducting quantum interface devices (SQUIDs) have enhanced the EC technique’s capability. Such sensors can be used to detect flaws that are located deep in aluminum plates. However, inspection of a defect located 12 mm to 25 mm below the surface of an aluminum plate is beyond the ability of conventional single frequency EC techniques.
