弹簧钢铸坯成分偏析定量分析方法
摘要：
本发明公开了一种弹簧钢铸坯成分偏析定量分析方法，包括如下步骤：1)横向截取弹簧钢铸坯草样；2)横向截取一定厚度的铸坯作为低倍样，进一步锯切成观测样；3)对观测面进行加工；4)选定一种化学元素，通过金属原位分析仪对观测面进行二维面扫描，得到选定元素在扫描区域内的分布图谱；5)通过图像处理软件，计算分布图谱上不同颜色所占的面积百分比，据此分析选定元素的在该观测面上的偏析程度，元素含量的分布越集中，越接近平均值，则选定元素在观测区内的偏析程度越低；按照步骤4)～步骤5)，对所有观测样及所有测试元素进行测定和处理。该方法能够准确反映铸坯化学成分在二维面上的分布情况；分析结果更全面、更精确。
摘要（英）：

The invention discloses a spring steel slab component segregation quantitative analysis method. The method comprises the following steps: (1) transversely intercepting a spring steel slab sample; (2) transversely intercepting a casting blank of a given thickness to be used as a low sample, and further sawing the low sample to obtain an observation sample; (3) processing an observation surface; (4) selecting a chemical element, carrying out two-dimensional scanning on the observation surface by virtue of a metal in-situ analysis instrument to obtain a distributive graph of the selected chemical element in the scanning area; (5) calculating the area percentage of different colors in the distributive graph by virtue of image processing software, analyzing a segregation degree of the selected element on the observation surface accordingly, wherein the element content is closer to an average value while the distribution of the element content is more concentrated, and the segregation degree of the selected element in the observation area is lower; determining and processing all observation samples and all test elements according to step (4) to step (5). By adopting the method, the distribution situation of the casting blank chemical components on a two-dimensional surface can be accurately reflected; an analysis result is more comprehensive and more precise.
