Summary:A large number of methods has been reported on the correction for matrix effect in fluorescent X-ray analysis of high-alloy steels, but many of them require very complicate calculations or a great number of standard samples. The method proposed here by the authors utilizes mass absorption coefficients and even a large number of correction factors are transformed into only two. Since a correction formula is readily obtained by relatively small number of standard samples and simple calculations, an accurate analytical value is easily obtained. The standard errors in estimation of chromium after corrections are 0.13% on tool steels, 0.10% on high temp. steels, and 0.14% on stainless steels.
