The aim of this research, part of a wider program called SPOFIC, is to investigate how the casting procedure affects the concentration of hydrogen and nitrogen gases in Compacted Graphite Iron used for the production of truck cylinder blocks. Hydris equipment was used for the Hydrogen measurements and the Optical Emission Spectroscopy and combustion analysis methods were used for the nitrogen measurements. The experiment was performed in one of the cooperating foundries. It was found that Hydrogen content is increased during pouring of the melt into the mold but nitrogen content does not seem to be effected by the process. In both cases the gas content never exceeded the solubility limit. The results are comparable with results from similar researches regarding Gray Cast Iron. / SPOFIC
