Description: 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 and subsequently graphite. Upon reaching the eutectoid temperature the austenite transforms to pearlite, giving a final microstructure consisting of graphite in a pearlite matrix.
