AI Technical Summary
In the existing technology, the quantitative analysis method for carbide content in high-temperature alloys is inaccurate and cannot effectively identify and distinguish them, resulting in insufficient accuracy of carbide content analysis results. This fails to effectively solve the problems of narrow applicability and low accuracy of the quantitative analysis method for carbide content in the existing technology.
High-temperature alloy samples were prepared using metallographic sampling. The mass percentage distribution of each element was measured by electron probe microanalysis. The surface distribution of the main elements was used, and the content of carbides was statistically analyzed by image analysis software. This simplified the sample processing steps and avoided chemical or electrolytic etching treatments.
It improves the accuracy and applicability of carbide content analysis, simplifies the operation process, reduces costs, and can effectively identify and distinguish complex carbides, especially those rich in W and Ta.
