摘　　要：以化学法标定的钛合金作为标准样品 ,用理论α系数及干扰曲线法进行基体效应和谱线重叠干扰的校正 ,开发了用X射线荧光光谱测定钛合金样品中除Ti外的常量和微量元素的方法。用该方法测定结果与化学值相符。 1 0次制样测量 ,各元素的RSD≤ 1 .2 5 %。A X ray fluorescence spectrometric method has been developed for the determination of Al, Si, V, Cr, Fe, Ni, Zr, Mo and Sn in various types of titanium alloys with synthesized standard samples. The inter element effect and line overlap are corrected by using the theoretical alpha coefficient and interfering curve method. The results are in agreement with values by chemical methods. The precision for each element is ≤1.25% RSD ( n =10).
