Cast Iron: Properties, Processing and Applications -

Malleable cast irons are formed via a slow annealing heat treatment of white cast iron. This results in the conversion of carbon, in the form of iron carbide in white iron, to graphite, with the remaining matrix being composed of ferrite or pearlite [1]. The graphite is present in the form of spherical or nodular shapes.
