Abstract

Cast iron exhibits a considerable amount of eutectic in the solid state. This article discusses the structure of liquid iron-carbon alloys to understand the mechanism of the solidification of cast iron. It illustrates nucleation of the austenite-flake graphite eutectic, austenite-spheroidal graphite eutectic, and austenite-iron carbide eutectic. The article provides a discussion on primary austenite and primary graphite. Depending on the carbon equivalent, the primary phase in cast iron can be either austenite for hypoeutectic cast iron or graphite for hypereutectic cast iron. The article also describes the growth of eutectic in cast iron in terms of isothermal solidification, directional solidification, and multidirectional solidification.
