The fundamental parameter (FP) method for the analysis of seven analytes (Al, V, Cr, Fe, Zr, Mo and Sn) in titanium alloys was investigated. The program used for calculation was the XRF-11. One homogeneous multi-elements home-made standard was made by the plasma electron-beam melting method using several press compactions which were prepared from various metal powders and sponge titanium. The chemical composition of the standard was determined by the JIS and TIS analytical methods. The spectral line overlaps were examined. The net count rate of the unalloyed titanium at the VKα peak angle was measured and that at the TiKα peak angle and the ratio (mV,Ti) between them was found to be 0.0064. The net count rate of the Ti-V binary alloys containing no chromium at the CrKα peak angle was measured and that at the VKα peak angle. The ratio (mCr,V) between them was 0.0101. For the determination of chromium the count rate for VKα must first be corrected for interference from TiKβ and then CrKα count rate corrected for interference from VKβ. The relative standard deviations of repetitive six measurments for the analytical values of the seven analytes were in the range of 0.30-1.43%. The determined values for NBS SRMs and IMI CRMs titanium alloys by the FP method agreed well with those certified values.
