Özet

Quantitative analysis of materials is significant for its potential usage in different areas. In the present study, quantitative analysis for Fe-Cr binary ferroalloys was evaluated by using Energy Dispersive X-Ray Fluorescence (EDXRF) system and the classical alpha-coefficient equation. The ferroalloys were prepared from powder form of Fe and Cr elements. The ferroalloys were excited by 59.54 keV gamma-rays from Am-241 annular radioactive source in EDXRF and K-alpha X-ray fluorescence spectra of Fe were analyzed in the binary matrices for determining analyte element Fe. Also, Wavelength Dispersive X-Ray Fluorescence (WDXRF) system was used to compare the concentrations of the analyte. The agreement was found to be quite satisfactory between the EDXRF and WDXRF (<= 1.76 relative difference (%) between concentrations), and it should be noted that the classical alpha-coefficient equation is highly reliable approach for quantitative analysis of ferroalloys. In addition, effective atomic numbers (Z(eff) ) of alloys were calculated using scattering ratio (R/C) method and fitted to concentrations obtained of alloys for fit equation.
