利用x光荧光光谱法测定镍基高温合金中的常量和微量元素时,由于成分复杂,除必须扣除谱线的重叠干扰外,还要对元素间的吸收—增强影响进行校正.本文在PW1600多道x光荧光光谱仪上进行了大量试验,在无理论α值的情况下,利用多元回归程序,求得元素间的影响系数α_(ij),从而用于各种牌号镍基合金成份的快速、准确分析. The determination of the constants and trace elements in nickel-based superalloy by X-ray fluorescence spectrometry, due to the complex composition, in addition to the need to deduct the overlapping interference spectral line, but also on the absorption-enhancement between elements to be corrected.In this paper, PW1600 and more X-ray fluorescence spectrometer on a large number of experiments, in the absence of theoretical α value of the case, the use of multiple regression program to obtain the impact coefficient between elements α_ (ij), which used in various grades of nickel-based alloy components of the fast, Accurate analysis.
