The study of the X-ray fluorescence analysis of titanium alloys by acid dissolution/glass bead technique has been performed. Synthetic bead samples were used for standards, which were prepared from the standard solutions of each analyte. Interference by coexisting elements was corrected by the Fundamental Parameter (FP) method, or the theoretical alpha coefficients method. Analytical results of the standard reference materials of titanium alloys samples (chip form) by the both methods showed in good agreement with the certified values. The analytical values for Al, V, Cr, Fe, Zr, Mo and Sn in the practical β-type titanium alloys were also in good agreement with the chemical analytical values. The Relative Standard Deviations (RSDs) of analytical values with the both methods were within 1.5%. Accuracy (σ_d) with the FP-method using one titanium alloy sample as a standard showed a little worse than that with the theoretical alpha coefficients method, but the FP-method was adequate for a rapid multielement analysis for titanium alloys.
