In order to clarify the effect of manganese addition on the formation of CO blowholes, a study has been made of uni-directional solidification at a solidification rate of about 5mm/min. The composition range explored was: C 0.08-0.12%, O 0.005-0.01%, and Mn 0.2-0.6%. The critical concentration of manganese for the formation of macroblowholes has been determined to be 0.29 to 0.31%. In the present study. about 0.01% of silicon contained in the starting specimen influenced the chemical reaction in the interdendritic liquid. The effect of oxygen on the critical concentration of manganese was small. The effect of manganese on the formation of macroblowholes could be explained by postulating chemical equilibrium in the interdendritic liquid. It is presumed that macroblowholes are formed with the similar mechanism as in the Fe-C-O and Fe-C-Si-O systems.
