The correlation that exists between elemental concentration ratios determined using EDX and EELS is examined. EELS and EDX were recorded simultaneously from the second phase carbides of a ferritic steel and the Cr/Fe and Mn/Fe concentration ratios were determined from each spectrum. For this system, it was found that the Cr/Fe ratios could be determined by EDX to within an accuracy of 4% and these were then used to provide a check on the EELS analysis procedures. The effects of using different partial ionization cross‐section models and methods of applying these models were examined. It was found that an overall agreement of 3% between EDX and EELS was obtained in this particular experiment. Much poorer agreement was found to exist between the two techniques for the Mn/Fe ratios. The discrepancy is attributed mainly to the inadequacies of the procedure used for extracting the Mn characteristic signal in the EELS spectra. 1987 Blackwell Science Ltd
