Further information
An example of a white cast iron, so named due to its relatively low carbon content, which means that the carbon present is in the form of cementite. Upon cooling the melt initially forms austenite dendrites and ledeburite. The dendrites then transform to pearlite, and the ledeburite to ferrite and cementite.
