Review of Progress in Quantitative Nondestructive Evaluation
Center for Nondestructive Evaluation

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 application of NMR imaging to problems in materials science, and in particular to nondestructive evaluation, has been hindered by a lack of appropriate NMR techniques to image rigid solids. NMR imaging of solids is made difficult by the typically broad NMR lines observed in the solid state. Molecular motion in liquids narrows the NMR line, making possible the high quality images obtained in medical imaging. The molecular motion present in some solids has been exploited to obtain NMR images materials such as elastomers [1,2]. Alternatively, the solid component of materials has been inferred from the absence of signals in NMR images of imbibed fluids. Here we discuss a class of NMR imaging methods which aim to reduce the apparent solid state linewidth to values approximating those in liquid samples.
