All investigated inoculants serve to produce vermicular graphite iron of a similar chemical composition. A qualitative identification of inoculant particles phase composition and surface microanalysis is carried out by electron-microscopic examination and X-ray spectral microanalysis. The investigations used can serve as an effective way of inoculants ranking according to their qualitative and performance characteristics.enArticle
