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
A brief summary of the progress of the research in the internal structural characterization of metal matrix (MMC) and ceramic matrix (CMC) composite materials is presented here. These materials show great potential for improving turbine engine performance by enabling operation at higher temperatures and stresses than now possible [1]. However, the application of these materials requires advances in NDE capability in order to characterize material parameters that are likely to affect performance. Several ultrasonic methods are being developed to characterize the internal structure of these anisotropic, inhomogeneous materials.
