Graphite flakes in grey cast iron
WebCast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured; white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and … WebFig: 1. The specific microstructure characteristic of gray cast iron is the existence of graphite in the form of flakes, as shown in fig:1. In this micrograph, the flakes (dark gray) are encircled by a array of pearlite. The array of an as-cast gray iron can also include of 100% ferrite, 100% pearlite, or numerous mixtures of pearlite and ...
