WebPearlite 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. … WebThis results in a thin surface layer in which the carbon content is 10 atom%. How far from the surface (in mm) will the carbon content reach 5 atom% ... At 750 °C the material is 100% austenite On cooling to 400 °C in 100 seconds the material goes through the pearlite region into the bainite region. This converts most of the material to bainite.
