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 presence of and/or the potential for cracks in powder metallurgy components is an industry recognized quality concern. In an industry wide survey, eliminating or controlling of cracks was found to be the second most important research priority identified [1]. The general improvement of mechanical properties was the number one issue identified. It should be noted, however, that the benefits of material properties gains only slightly exceeded that of the cracking issue in importance to the industry respondents of the surveys.
