In this work, a model is proposed for heterogeneous nucleation on substrates whose size distribution can be described by the Weibull statistics. It is found that the nuclei density, N_[nuc�] can be given in terms of the maximum undercooling, [...]. When nucleation occurs on all the possible substrates, the graphite nodule density, N_V,n or eutectic cell density N_V after solidification equals N_s. In this work, measurements of N_V,n and N_V values were carried out on experimental nodular and flake graphite iron castings processed under various inoculation conditions. The volumetric nodule N_V,n or graphite eutectic cell N_V count, were estimated from the area nodule count, N_A,n or eutectic cell count N_A on polished cast iron surface sections by stereological means. In addition, maximum undercoolings [...]
