Thin-walled nuclear fuel cladding tubes made of AISI 316 stainless steel have been examined by eddy-current testing. Standardization of the procedures has required investigations on optimizing the test frequency, finding a method to locate a defect with respect to the probe reference end, and the ...
This project, and indeed, this entire thesis is principally based on electromagnetic testing methods. An eddy current technique for mapping the microstructural phases was produced and validated as far as was achievable; this offered a significant time-saving advantage over the previous method, by ...
(features at this scale are still attenuated by a factor of about two (CSS11); an amplitude unattenuated by the mapping procedure is found at scales of 0.6° and larger.) As a result, oceanographers tend to limit their analysis to features that persist over a month and span at least 8...

1. A method for testing the hardness of a metallic sample having a surface, comprising: inducing eddy currents in said sample with a probe generating an alternating current magnetic field, providing a signal produced by the eddy currents in said sample, ...
in which deviations in the conductivity of the part indicates an improper mixture of alloyed metals, and/or incorrect heat treatment. Conductivity can also be used to determine the grade or temper of the alloy. Eddy-current conductivity testing is widely used in the manufacturing of aircraft compo...
an eddy current probe may be integrated within a chemical mechanical polishing (CMP) tool. In this application, the eddy current probe is utilized to detect one or more endpoint(s) of one or more etched layers. By way of
