Description
技术领域technical field
本发明属于高温合金材料成分分析技术领域，涉及一种定量评价高温合金中合金元素偏析的分析方法。The invention belongs to the technical field of component analysis of high-temperature alloy materials, and relates to an analysis method for quantitatively evaluating the segregation of alloy elements in high-temperature alloys.

Different alloying elements play different roles, such as solid solution strengthening, second phase strengthening and grain boundary strengthening and so on. The quantity, composition, size, distribution of various phases and the distribution of alloying elements at grain boundaries have a great relationship with the mechanical properties and corrosion resistance of superalloys. Therefore, the segregation law of alloying elements in superalloys is studied and predicted The state of segregation is of great significance for the process optimization of superalloy production.
高温合金元素偏析的传统分析方法中元素偏析行为主要用析出相来间接表征，通过扫描电镜、X射线衍射仪、透射电镜、能谱仪等对析出相的形貌、物相、成分进行分析，以此来间接评价元素偏析行为。In the traditional analysis method of superalloy element segregation, the element segregation behavior is mainly characterized indirectly by the precipitated phase, and the morphology, phase and composition of the precipitated phase are analyzed by scanning electron microscope, X-ray diffractometer, transmission electron microscope, energy spectrometer, etc. In this way, the element segregation behavior can be evaluated indirectly.
缪乐德等在《冶金分析》第35卷第1期公开的《不同热处理状态下镍基耐蚀合金析出相的定性定量分析》中主要是利用化学法电解出析出相，并得到其成分的定量结果。但是该法仅能得到析出相的成分，不能显示出各元素在样品中的分布位置。郭岩等在《中国电力》第45卷第1期公开的《INCONEL617合金的高温时效析出相》中主要是利用透射电镜和扫描电镜对析出相进行了研究，同样无法得出各元素在不同位置的偏析情况。In the "Qualitative and Quantitative Analysis of Precipitated Phases of Nickel-based Corrosion-resistant Alloys under Different Heat Treatment States" published in "Metallurgical Analysis" Vol. Quantitative results. However, this method can only obtain the composition of the precipitated phase, and cannot show the distribution position of each element in the sample. In the "High Temperature Aging Precipitated Phases of INCONEL617 Alloy" published in Volume 45, Issue 1 of "China Electric Power", Guo Yan et al. mainly used transmission electron microscope and scanning electron microscope to study the precipitated phases. of segregation.
从上述文献专利中看出，现有的分析偏析技术存在需要标样，且对元素含量有限制，结果不直观；各元素在样品中的分布不明确等缺陷。It can be seen from the above-mentioned literature and patents that the existing analytical segregation technology has defects such as the need for standard samples and restrictions on element content, the results are not intuitive, and the distribution of each element in the sample is not clear.

下面结合实施例进一步说明本发明。Below in conjunction with embodiment further illustrate the present invention.
1)将825合金试样进行热镶嵌，利用磨抛机进行180#、800#砂纸粗磨，1200#、1500#砂纸细磨，然后经过5μm、1μm金刚石抛光剂，抛光至无明显划痕后，迅速在无水乙醇中洗净，并用电吹风吹干；1) Thermally mount the 825 alloy sample, use a polishing machine to perform rough grinding with 180#, 800# sandpaper, fine grinding with 1200#, 1500# sandpaper, and then pass through 5μm, 1μm diamond polishing agent, and polish until there is no obvious scratch , quickly washed in absolute ethanol, and dried with a hair dryer;
2)将硫酸铜、盐酸、蒸馏水按照mCuSO4:VHCl:VH2O＝1:5:5的比例配制腐蚀液，将样品浸泡在溶液中，抛光面面向容器侧壁，观察样品表面状态，2.5分钟后取出样品，迅速在无水乙醇中洗净，并用电吹风吹干，并在扫描电镜观察析出相的分布，如图1所示，白色颗粒为析出相；2) Copper sulfate, hydrochloric acid, distilled water are prepared corrosion solution according to the ratio of m CuSO4 :V HCl :V H2O =1:5:5, the sample is immersed in the solution, the polished surface faces the side wall of the container, and the surface state of the sample is observed, 2.5 After 10 minutes, take out the sample, wash it quickly in absolute ethanol, and dry it with a hair dryer, and observe the distribution of the precipitated phase under a scanning electron microscope, as shown in Figure 1, the white particles are the precipitated phase;
3)利用高真空喷碳仪在样品表面溅射碳膜，在上述腐蚀液中脱膜，置于蒸馏水中反复清洗碳膜，最后将碳膜烘干；3) Use a high-vacuum carbon sprayer to sputter a carbon film on the surface of the sample, remove the film in the above-mentioned corrosive solution, place the carbon film in distilled water to clean it repeatedly, and finally dry the carbon film;
4)将复型样品置于扫描电镜中，利用能谱仪分析析出相的成分，确定电子探针所需分析的合金元素；4) Place the replica sample in a scanning electron microscope, use an energy spectrometer to analyze the composition of the precipitated phase, and determine the alloy elements to be analyzed by the electronic probe;
5)样品再次用5μm、1μm金刚石抛光剂进行抛光处理，直至表面的腐蚀痕迹消失。通过电子探针对重新抛光后的试样进行表面观察，对试样表面进行波谱面分析，如图2所示，电子探针波谱面分析区域与复型区域要相对应；5) The sample is polished again with 5 μm and 1 μm diamond polishing agents until the corrosion traces on the surface disappear. Observe the surface of the re-polished sample with an electronic probe, and perform spectral analysis on the surface of the sample. As shown in Figure 2, the electronic probe spectral analysis area should correspond to the replica area;
6)电子探针数据采集时，设置的参数如下：加速电压为15kV，电流为100nA，分析步径为0.05μm，提取晶界与晶内的合金元素的成分数据测试多个晶粒，求平均值；6) When collecting electronic probe data, set the parameters as follows: the acceleration voltage is 15kV, the current is 100nA, the analysis step is 0.05μm, and the composition data of the alloy elements in the grain boundary and the grain are extracted to test multiple grains and calculate the average value;
分析结果处理如下：The analysis results are processed as follows:
分别提取多个区域的晶界与晶内的数据，取其平均值，计算出晶界与晶内的元素的浓度分配系数K，并作出与热处理时间的关系曲线图，如图3所示：The data of grain boundaries and grains in multiple regions were respectively extracted, and the average value was taken to calculate the concentration distribution coefficient K of elements in grain boundaries and grains, and the relationship curve with heat treatment time was drawn, as shown in Figure 3:
K＝晶界平均计数(元素)/晶内平均计数(元素)K = grain boundary average count (element) / grain average count (element)
根据曲线图即可定量的评价随着热处理温度的变化，所选的825合金试样中合金元素在晶界与晶内的偏析规律：元素Cr、Mo随着热处理温度的增加先向晶界迁移再向晶内移动，而元素Fe、Ni正好相反，随着热处理温度的增加先向晶内迁移再向晶界移动。According to the graph, we can quantitatively evaluate the segregation law of alloy elements in the grain boundary and in the grain of the selected 825 alloy sample with the change of heat treatment temperature: elements Cr and Mo migrate to the grain boundary first with the increase of heat treatment temperature Then it moves into the grain, while the elements Fe and Ni are just the opposite. With the increase of heat treatment temperature, they first migrate into the grain and then move to the grain boundary.
