EDS Round-Robin Evaluation of Type 308 Austenitic Stainless Steel

摘要

Compositional analysis using transmission electron microscopy and EDS detectors has made significant advances in the last decade, with regard to both equipment available and data analysis procedures. Concentrations determined using this technique are commonly quoted in the literature. However, a large variety of hardware and software is presently available and standard procedures for specimen preparation, data acquisition, and data reduction have not been established. Therefore, detailed comparisons of results from different sources may not be very accurate. Purpose of this investigation was to evaluate the variations that may exist in compositional evaluations that are performed by different investigators using different equipment. A round-robin analysis of identical specimens was initiated and the results are reported. (ERA citation 09:040666)
