Influence of technological parameters on the microstructure of the silicon cast iron

Factors influencing the crystallization process (e.g. chemical composition of the alloy, casting conditions, conditions of heat dissipation from the mold, etc.) in conjunction with a set of data recorded during the solidification and crystallization processes, and data describing the morphology of the stereological parameters of the alloy will complete the missing knowledge about the influence of the kinetics of high-silicon iron crystallization on its microstructure. This would involve intermetallic phases such as Fe5Si3 characteristic of alloys with high Si content. Literature touching this subject is poor, these positions often date back to the second half of last century, and the information contained in some cases is mutually exclusive. After crossing the border of 15 % Si in the alloy we deal with contradicting information about the microstructure of the matrix. Regarding the crystallization process and the impact of conditions on the formation of these phases the literature is unavailable or gives insufficient data, which is not satisfactory. Therefore, this study presents a crystallization process in various conditions for high silicon cast iron alloys.
