Pearlite is a two-phased, lamellar (or layered) structure composed of alternating layers of ferrite (87.5 wt%) and cementite (12.5 wt%) that occurs in some steels and cast irons. During slow cooling of an iron-carbon alloy, pearlite forms by a eutectoid reaction as austenite cools below 723 °C (1,333 °F) (the eutectoid temperature). Pearlite is a microstructure occurring in many common grades o… WebAug 15, 2008 · Gray cast iron (GCI) is traditionally chosen in many industrial applications because of its flexibility of use, good castability, low-cost (20–40% less than steel) and … teh untuk menurunkan berat badan
