It also assures that Type A graphite will precipitate out of the molten iron.
The slower solidification and cooling of heavier castings results in the formation of coarser graphite flakes and a softer matrix structure that combine to lower iron strength.
The graphite structures of gray and ductile cast irons significantly affect the physical properties of these metals.
Graphite flakes have a weakening effect on iron stregth.
The graphite, up to this precipitation point, has been dissolved in the molten gray iron as elemental carbon, but the introduction of the inoculant facilitates the carbon coming out of solution as graphite when the eutectic freezing point is reached as the metal cools.
Proper inovulation assures that enough nucleation sites are formed to precipitate graphite flakes sized and configured to satisfy the metallurgical requirements of the iron alloy being cast.
Even after solidification, graphite can continue to grow slightly in volume as the solubility of carbon in austenite is reduced and the rejected carbon migrates to existing flakes or nodules.
Inoculation compnesates for this by providing graphite flakes of more uniform shape and size throughout the casting.
The longer period encourages graphite nucleation and graphite flake growth.
