本文介绍了用光学特殊技术和扫描电子显微镜等不同方法对Ti-6Al-2Mo-2Cr-Fe两相合金显微组织的研究结果。结果表明，对于α相的颗粒尺寸和片层集落的评价，在偏振光下用波长滤光片观察得到的结果最好。给出了能够检测板层菌落边界的图像变换算法。它根据CMYK模型将彩色图像分成基本颜色。此外，还提出了一种用于定量分析的扫描电子显微镜图像的全自动制备方法。
The paper presents the results of investigations of the two-phase Ti–6Al–2Mo–2Cr–Fe alloy microstructure by means of different methods: special techniques of light and scanning electron microscopy. It has been found that for the evaluation of the grain size and lamella colonies of the α phase, an observation in polarized light with a lambda filter gives the best results. The algorithm of the image transformations enabling detection of boundaries of the lamella colonies is presented. It employs color image separation into basic colors according to the CMYK model. Also, a fully automatic way is presented for the preparation of images obtained by means of a scanning electron microscope for quantitative analysis.
