The effects of sulfur, titanium and zirconium on the shape of eutectic solidification front in gray cast iron were investigated by interrupting unidirectional solidification. The specimens contain 0.012, 0.108, 0.37mass%S, 0.177mass%Ti, 0.078mass%Zr respectively. They are 80 g in weight. 17mm in diameter. and 55mm in length. The temperature gradient at the solid-liquid interface is about 25 K/ cm. The oscillatory model for graphite branching is proposed by considering the shape of the solidification front and protuberance length of the graphite flakes.
