ENERGY DISPERSIVE X-RAY FLUORESCENCE (EDXRF) ANALYSIS OF STEELS

A powerful, simple and fast technique for non-destructive multi-element analysis of materials is energy dispersive X-ray fluorescence (EDXRF) technique. This method is based on radioisotope excited energy dispersive X-ray fluorescence (EDXRF) spectrometry and does not require any type-standards. For these reasons, the EDXRF method was chosen in this paper to analyse the different types of stainless steel (SS) samples. After non-destructive multi-element analysis of samples revealed that Si (0.1–0.52), S (0.01-0.12), K (0.25-0.86), Cu (0.19-0.24), Ca (0.01-0.03) etc are present as minor components while Cr (15.1-17.5), Mn (0.56-1.4), Fe (69.8-83.7), Ni (0.03-10.4) are present as major components.
