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 goal of this work is to develop a technique for on-line monitoring of surface topography. The monitoring of aluminum surfaces must provide reliable and fast distinction between “good” and “bad” surfaces. This project has investigated the feasibility of the ultrasonic reflection coefficient to measure differences in surface roughness. The standard deviations for the surfaces are 10–20 μm.
