Abstract：In order to realize the rapid and quantitative statistical distribution characterization of the components in profile of large-size wheel, the quantitative distribution characterization method of composition in high-speed rail wheel was investigated based on the spark source original position statistic distribution analysis technology. Then this characterization method was applied to the quantitative statistical distribution analysis of composition in the rim profile of three types of high-speed railway wheels (W1, W2 and W3). The quantitative distribution law of chemical composition from the vicinity of tread to the inside of rim was obtained. Moreover, the difference in element segregation behavior among the three wheels was discussed. Combining the characterization results of inclusions and metallographic structure of the rim by scanning electron microscopy (SEM) and energy spectrum analysis, it was found that the presence of inclusions had a significant influence on the uniformity of element distribution in wheel, which was the main reason for the high statistical segregation degree of the corresponding elements. There were a large amounts of ductile strip-type MnS inclusions in the W2 wheel, and the maximum length of sulfide exceeded 100 μm. Therefore, the statistical segregation degrees of Mn and S were significantly higher than those of other wheel samples. Meanwhile, the existence of some abnormal upper bainite structure in the wheel was the intrinsic reason for the high statistical segregation degree of C element in the W1 wheel sample.
