metallurgy of steel - NPTEL

1.2 Metallurgy of steel When carbon in small quantities is added to iron, 'Steel' is obtained. Since the influence of carbon on mechanical properties of iron is much larger than other alloying elements. The atomic diameter of carbon is less than the interstices between iron atoms and the carbon goes into solid solution of iron. As carbon dissolves in the interstices, it distorts the ...

Example: In iron ore, sand SiO 2 is the main gangue. The term 'Flux' refers to the compound added during extraction, which reacts with a non fusible (high melting point) gangue and forms a fusible product called slag. This can then be removed by simple physical method. Example: In the blast furnace for extraction of iron, the flux added is limestone CaCO
