Normalized Distribution Coeficient as a Novel Method for Cast Irons Matrix Heterogeneity Assessment

Popis výsledku v původním jazyce

This contribution deals with the comparison of different methods of alloying elements concentration measurement based on energy dispersive spectroscopy and also with the suitability of particular methods of quantitative assessment of heterogeneity of thespheroidal graphite cast iron matrix. The segregation curves construction and distribution coefficient formulation is also discussed. Based on a basis, which is to be achieved by means of evaluation of large experimental data sets, is the evaluation ofapplicability of homogenization annealing of spheroidal graphite cast iron with the aim to eliminate segregation of silicon, and mainly nickel, as pearlite- and carbide-forming agent at the border of eutectic cell. The result is an optimized homogenization annealing schedule maximizing the suppression of silicon and nickel segregation while taking into account the minimization of financial expenses and risk of grain coarsening. For quantitative evaluation of the distribution of alloying
