3P1 Solidification and Microstructure of a Casting
Graphite is a low density phase so the formation of graphite counteracts the contraction of the iron on solidification. For near-eutectic compositions of grey cast iron there is effectively zero volume change on solidificationuseful for producing castings directly to final size and shape.

PearliteWikipedia
Pearlite is a two-phased lamellar (or layered) structure composed of alternating layers of ferrite (87.5 wt ) and cementite (12.5 wt ) that occurs in some steels and cast irons.During slow cooling of an iron-carbon alloy pearlite forms by a eutectoid reaction as austenite cools below 723 °C (1 333 °F) (the eutectoid temperature). Pearlite is a microstructure occurring in many common grades
