1 The alloys known as cast iron contain in addition to iron, carbon, and silicon, appreciable percentages of manganese, sulphur, and phosphorus, which are added to improve the qualities of the resulting metal. Nickel, chromium and molybdenum may also be present in cast iron as specific alloying elements. With the possible exception of carbon, the chemical elements are not present in the purl stats cast iron, but are contained in combinations in the physical constituents of the metal.
2 Micro-constituents of cast iron. The proper ties of cast iron are dependent directly upon the proportion and condition of its structural constituents. The amounts of these constituents can be computed approximately from chemical analysis and their size and distribution can be established by microscopic examination. The characteristics of the microconetituents ordinarily found in cast iron will now be discussed.
3 Ferrite. Ferrite is composed largely of iron with small proportions of iron silicide (FeSi) and iron phosphate (Fe3P) in solution with the iron in the solid state. This constituent is soft and ductile, strongly magnetic and has a tensile strength of 40 000 to 50 000 Lb.per sq.in. and an elongation between 40 and 50 per cent. It has a Brinell hardness of about 80. Under the microscope, ferrite appears as light colored grains having irregular shapes.
4 Graphite. Graphite is relatively pure carbon occurring in the form of flakes or small particles in gray cast iron. This constituent is soft and improves the machinability of iron. The proportion of graphite in cast iron is dependent upon the chemical composition, as well upon the rate of cooling of the metal. The mechanical properties of gray cast iron are influences largely by the amount, size, and distribution of the graphite particles. The larger and more continuous the graphite flakes, the lower will be tensile strength.
