... for the practicing metallurgist involved in cast iron production. The primary phase can be either austenite for hypoeutectic cast iron or graphite for hypereutectic cast iron. Further solidification into eutectic structures can be either an austenite-graphite eutectic or an austenite-cementite (Fe 3 C) eutectic...
