EXTENDED ABSTRACT: The combinatorial-sample is an important way to quickly obtain many different materials in material genome engineering filed and high throughput characterization can efficiently obtain material data of combinatorial sample. The accurate quantification and rapid characterization of components in combinatorial-sample determine the correct relationship model between material compositions, microstructures and properties. The accurate quantification of material components usually requires chemical analysis methods, but it is difficult to prepare sample and perform chemical analysis on samples of each component because combinatorial-sample is generally manufactured into multicomponent small size states. Therefore, energy dispersive spectroscopy of scanning electron microscope (SEM-EDS),electron probe micro analysis (EPMA) and micro beam X-rayfluorescence spectroscopy (u-XRF) are often used to detectthe components of samples. The accuracy of these relativeanalysis methods depends heavily on the calibration curvesused. Since the calibration curve preset in the analyzer is auniversal curve, there are often some analytical errors formaterial quantification due to the interference of multiplespectral lines, matrix effects and so on. n addition, therepeatability of analytical data is also an important factorin quantitative results, which mainly depends on the optimization of instrument parameters. In this paper. aiming at honeycomb structure combinatorial-sample (containing 106nickel base superalloys with different components) manufactured by high throughput hot isostatic pressing, a high throughput component characterization of micro beam XRF was developed. And the effects of voltage, current, integration time, spectraltine interference, beam spot size of XRF and a series of standard samples on the repeatability and accuracy of the analysisresults were systematically studied. The high throughput component distribution characterization of the combinatorial-sampewas realized with a diameter of about 20 um beam spot during about 12 hours. The high-throughput component quantitative characterization was realized with a diameter of about 1 mm beam spot during less than 1 hour. The paper discussed theanalysis accuracy of -XRF and EDS which provides a strong guarantee for the validity research of scientifc research data.
