摘要
In this work, the results of the examinations of morphology and chemical composition of the primary AITMSi intermetallic phases precipitates observed in the Al Si cast alloys microstructure have been presented. A procedure for the treatment of EDS X-ray microanalysis results (selection and classification) using fuzzy logic concept has been developed and then tested in application for AITMSi phase identification. Statistically significant differences in the chemical composition have been revealed between the analyzed groups of precipitates of both alpha-and beta-AITMSi phases formed in hypo- and eutectic Al-Si alloys with the same content of transition metals. The range of the measured Mn solubility in the precipitates of different crystal lattices has been statistically estimated.
