Aging of Graphitic Cast Irons and Machinability

ABSTRACT
In 1999, researchers at the University of Missouri-Rolla demonstrated that age strengthening occurs in gray cast iron. In 2002, these same researchers found that the machinability of cast iron improves with age strengthening, and have shown evidence of a 0.2-0.4 nm precipitate formation by neutron scattering. With age strengthening determined in gray cast iron, researchers are looking for similar results in ductile iron.
