Abstract: The eutectic growth of cast iron during rapid solidification has been studied with laser remelt- ing and deep etching technology.A new mode of mushroom eutectic growth was observed oth- er than the usual honeycomb and lamellar ones.The mushroom eutectic growth may finally form the lamellar dendritic structure.

Key words: cast iron, eutectic growth, rapid solidification
