The cast iron melts containing about 3.5% C and about 1.8% Si were cast in small moulds of current use in the previous experiments after addition of Ti in the form of metallic Ti, ferro-Ti and of Cu-Ti alloy. In the present scope of experiments, gray cast irons having the same eutectic graphite structure may be prepared in the present case as in the previous experiments where cast iron melts have been treated with the slag containing TiO_2, as far as more than 0.05% Ti was contained in the cast metal in the form of TiC and the melts were cast at the temperature lower than 1400℃. It is doubtful, however, that the above mentioned result will be always obtained also when the larger mould is used for casting.
