Basics of Ferroalloys
At that time metallurgists started to consider the addition of alloying elements to steel in the form of a ferroalloy—an alloy of iron with at least one other element (except carbon, which is as cementite, Fe 3 C, or graphite in cast irons). Small-scale production of ferroalloys began in the 1860s with the use of the crucible process.
