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.
Ultrasonic nondestructive evaluation (NDE) techniques for characterizing material properties in manufactured products are becoming valuable tools for detecting anomalies early in the manufacturing process. In particular, a system for on-line characterization of the microstructure in rolled sheet metal is already available for predicting formability parameters . Other key mechanical properties that are very sensitive to the microstructure such as yield strength and hardness are currently being measured off-line using slow and expensive destructive tests. As on-line techniques become available, it will become possible to detect sub-standard properties before large quantities of low grade material were produced.
