HISTORY OF METALLURGY
The age of iron: from 1500 BC: The next great development in metallurgy involves a metal which is the most abundant in the earth's surface but which is much more difficult to work than copper or tin. It is iron, with a melting point too high for primitive furnaces to extract it in pure form from its ore.

Cast irons are iron-carbon (and silicon) alloys having carbon or carbon equivalent value, more than 2% (actually it is 2.1 1%), i.e., more than the maximum solid solubility of carbon in austenite such that the eutectic reaction occurs during solidification. As the higher carbon contents make them more brittle, industrial cast irons have carbon ...

Cast iron is derived from pig iron, and while it usually refers to gray iron, it also identifies a large group of ferrous alloys which solidify with a eutectic. The colour of a fractured surface can be used to identify an alloy. White cast iron is named after its white surface when fractured, due to its carbide impurities which allow cracks to pass straight through.
