CHILLED CAST IRON Chilled-Iron castings are made by casting the molten metal against a metal chiller, resulting in a surface of white cast iron. This hard, abrasion-resistant white-iron surface or case is backed up by a softer gray-iron core. This case-core structure is obtained by careful control of the overall alloy composition and adjustment of the cooling rate. A chilled-iron casting may ...Mechanical and Microstructure Properties of .Mechanical and Microstructure Properties of Chilled Cast Iron Camshaft - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Mechanical and Microstructure Properties of Chilled Cast Iron .Classification and B!asic Metallurgy of Cast Irons• Chilled iron is white iron that has been pro-duced by cooling very rapidly through the so-lidification temperature range. • Mottled iron is an area of the casting that so-lidifies at a rate intermediate between those for chiHed and gray iron, and which exhibits microstructural and fracture-surface features of .Microstructures of iron-carbon alloysCast Irons Cu Al Mg Ti <1.4wt%C 3-4.5wt%C 1600 1400 1200 1000 800 600 400 0 1 234 566.7 L γ austenite γ+L γ+Fe3C α ferrite α+Fe3C α + γ L+Fe3C δ (Fe) Co, wt% C Eutectic: Eutectoid: 0.77 4.30 727°C 1148°C T(°C) Steels <1.4wt%C Cast Irons 3-4.5wt%C microstructure: ferrite, graphite cementiteHeat Treatment of Cast Ironsgeneral term cast iron includes pig iron, gray iron, malleable iron, chilled iron, white iron, and nodular or ductile iron. If an iron alloy exceeds about 2% car-bon, the carbon does not have to nucleate from decomposition of austenite, but instead, it can form directly from the .
