WC-Co硬质合金微观结构随机性表征
Randomness Characterization of Microstructure of WC-Co Cemented Carbides
摘要
Abstract
In order to characterize the randomness of microstructure of WC-Co cemented carbides, Matlab and VC++ were hybrid programmed to analyze the scanning electron microscopy (SEM) images of the microstructure, and the outline of the microstructure was extracted. Then the microstruc-tural topology parameters were calculated, and the distribution regularity of the microstructural parameters was statistically investigated. The results show that, the average grain diameter, major axes and minor axes, centroid, orientation angle, and Co volume fraction of WC-Co cemented carbides can be accurately measured by using the image processing software. Moreover, the randomness characterization of the microstructure of WC-Co cemented carbides can be well accomplished by using probability density function.关键词
