Abstract The "carbon peaks" and high carbon activity spots appear in molten cast ironduring inoculation by Si. No evidence shows that the number of Si-rich particles whichmight be the heterogeneous nuclei of graphite is increased by inoculation. It is suggested thatthe mechanism of inoculation is the undulation of C concentration and activity in an inocu-lated cast iron. The fading of inoculation is caused by the fading of undulation.

Key words: cast iron inoculation catbon activity electron probe microanalysis
