Iron Carbide (Fe3c) - an overview | ScienceDirect Topics

Iron carbide (Fe 3 C) is often labeled as the uncorroded portion of the steel. It is primarily associated with mild steels having a high carbon content and a ferritic-pearlitic microstructure. During corrosion of such steel, the ferrite phase dissolves and a porous iron carbide network is exposed (see Fig. 7.6).Given that iron carbide is an electronic conductor, this porous network serves as ...

Gray Iron | Iron Casting Research Institute, Inc.

The phosphorus content of most high-production gray iron castings is less than 0.15 percent with the current trend toward more steel in the furnace charge; phosphorus contents below 0.10 percent are common. Phosphorus generally occurs as an iron iron-phosphide eutectic, although in some of the higher- carbon irons, the ternary eutectic of iron ...

Bessemer process - Wikipedia

The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.
