For the past several years the Boeing Aerospace Company has been implementing advanced nondestructive chemical analysis methods to improve product reliability and reduce material inspection costs. Previous testing of incoming material for conformance to vendor test reports or of production materials for verification of alloy composition, had consisted of either time-consuming destructive testing or nondestructive chemical spot testing, which often was insensitive to differences between alloys of similar chemical properties. Beginning in 1974, development of EDXRF techniques was initiated to provide a rapid nondestructive analysis capability for both laboratory and factory use. For materials containing elements easily excited by EDXRF methods, costly destructive sampling and testing can be avoided. Generally, chips, wire, barstock, sheet or plate can be analyzed using an annular radioactive source. The uniformity of the X-ray flux diminishes sample geometry and surface roughness effects.

Abstract Radioisotope x-ray fluorescence spectrometry was investigated as a potential screening method for Pb and other elements in housewares. Thirty-six commercial houseware items and 87 ceramic test tiles (85 fired with hobby glazes and 2 blank bisques) were examined qualitatively for the presence of Pb by using 109Cd-induced L x-ray fluorescence emission spectrometry. For the housewares, the technique provided fast, nondestructive analysis of areas with about 10 cm diameters (general regions) to about 4 mm diameters (isolated design regions). Pb was found in 25 of 28 ceramicware items, in all 8 other housewares, and in all the testtile glazes above the limit of detection of 1 count per second (cps) for Pb Lβ x-rays. For housewares, Pb identification did not always correspond to Pb leachability. For 68 test-tile glazes labeled as containing Pb (39 of which were also labeled ‘dinnerware safe’ or ‘safe for food containers’), count rates ranged from 290 to 730 cps, whereas for the other 17 glazes labeled (with one exception) ‘nontoxic,’ much lower count rates (5–61 cps) were obtained. Other elements found in the housewares or test glazes were As, Au, Ca, Co, Cr, Cu, Fe, Mn, Nb, Ni, Rb, Sr, Y, Zn, and Zr.

There are currently no plans for the commercial reprocessing of nuclear fuel in the U.S. This is not the case in Japan, England, France, Germany, or the USSR. The U.S. does, however, include the reprocessing of spent nuclear fuel as a part of its defense programs. The Office of Safeguards and Security of DOE's Defense Programs has funded the development and optimization of numerous nondestructive analysis techniques including K-edge x-ray fluorescence analysis. This paper reviews some of the implementation efforts resulting from R&D supported by that office.In 1979, the concept of using K-edge x-ray fluorescence analysis (K XRFA) for the analysis of actinide solution concentrations was first presented. K XRFA using small radioactive Co-57 sources has been shown to be a practical way to measure actinide solution concentrations in offline, at-line, or on-line configurations. The experimental methodology is elegant and the hardware is simple.

Abstract Now we are attempting to apply non destructive analysis from evaluation tests or failure analysis to acceptance tests or production tests. Needless to say non destructive analysis has an advantage of conserving the state of samples and the reducing the time of analysis as compared to conventional methods with destructive physical analysis. Moreover, we are paying attention to the following reasons for nondestructive physical analysis. It is difficult to keep the reproducibility of the analysis because of the high skill level required for destructive physical analysis. On the other hand, high reproducibility can be easily achieved by fixing the condition or parameters of the device during nondestructive analysis when performed by tools like X-ray. Moreover, we expect that neither the analytical result nor the quality of the nondestructive analysis depends upon the worker's capability. In this paper we will discuss the following two items from the viewpoint of quality assurance. 1. The method of the screening for fake parts (1) The procedure flow for the production discontinued parts (2) The comparison and examination between the diagnostic using X-ray computed tomography (X-ray CT) images and various examinations (3) Other observation cases using X-ray CT images 2. Effectiveness and consideration in reliability evaluation test using X-ray CT image (1) Comparison of observation cases with a variety of jointing points in parts (2) Consideration of application of nondestructive observation technique in reliability test Use of X-ray CT images is effective in diagnosing the quality of the product or the process. Moreover, we find that use of X-ray CT images is effective for the improvement of the reproducibility of the evaluation examination. Then we find that use of X-ray CT images can reduce the time of evaluation examination too.

Time Domain Reflectometry (TDR) is a powerful measurement technique that uses the reflection of a pulse sent down a transmission line to characterize the impedance of that line. The voltage of a reflection will vary depending on the distance to the fault and on the amount of energy reflected. In this paper we develop a simple and effective electrical nondestructive analysis (NA) system for the evaluation of the interconnection of wire-bonded plastic ball grid array (WB-PBGA) package. An open-end fixture (OEF) was employed to connect fast rising edge signals to the package which was monitored for its time delay and reflection voltage parameters. This technology represents a valuable new method for the NA of WB-PBGA packages, and it has enabled the rapid and efficient detection and location of faults. Comparative TDR measurements accurately predicted the location of opens and short circuits in the copper traces of the substrate, bond wire, and solders balls. The TDR analysis was verified by using X-ray analysis. The paper establishes the use of a TDR system incorporating an open-end fixture for locating opens and shorts in WB-PBGA packages.

Abstract A woman’s crown made of fine gilt bronze with refined glass inlay work was excavated in 2007 from the Sui-Tang tomb called Kunlun M2 in Xi’an. Many questions surround this mysterious crown which was found buried without context. This study uses nondestructive analysis of the crown to determine its significance, when was it made, and the status of the woman for whom was it made. Optical microscopy (OM), optical coherence tomography (OCT), micro X-ray fluorescence imagery (XRF), and Raman spectroscopy were applied, and identified the crown’s inlays as potash-lime glass, composed mainly of the raw materials include vein quartz or quartzite with potassium nitrate as flux. The inlays were sintered before embedding into gilt copper wire filigree. Compared with existing research on other crowns and their inlays, it is speculated that the crown dates from the Sui dynasty (581-618) or early Tang dynasty (618-649), was made locally by Chinese craftsmen and belonged to the wife of an official.

The painting materials and drawing techniques of a pair of two-panel folding screens entitled Red and White Plum Blossoms by Ogata Korin, a national treasure in Japan, were investigated directly and nondestructively by XRF, X-ray radiography, and high resolution digital imaging. Several assumptions were made about the materials used in the red and white plum trees drawn on the right and left screens, respectively, and the river drawn at the center. By the present investigation, the materials used for the paintings were revealed, and some of them contradicted what have been previously believed.
