Numerous modern steel grades contain increasing quantities of both silicon and manganese. Silicon is commonly seen as a powerful ferrite former and hence expected to constrict the hypoperitectic range. Extensive DSC measurement on Fe-C-Si-Mn samples and commercial steel grades proved a less significant impact of silicon on carbon steel grades, but a strong interaction with manganese-alloyed steel grades during solidification. Plant observations on a slab casting machine confirm these results. These new findings are currently used to assess thermodynamic databases and will allow more precise solidification calculations in the future.
