1. Ferrite is the name of the structure of a solid solution of steel at 1200 F that contains a
very small percentage of carbon (perhaps 0.02% ).Assume that this steel has not been
previously heat treated.

The study of metallurgy actually explores what make
metals behave the way they do
Steel in itself is an alloy of at least carbon and iron.
Various other elements are added to obtain different performance

1. I ron and carbon are two elements found in every type of steel.
2. The percentage of carbon is in the steel from 0% to approximately 2%.
3. Most steel contains more than 90% i ron.
4. As the carbon content in steel increases , does the steel

2. Tempering is the process of reheating metal immediately after quenching for
t he purpose of increasing ductility or relieving stress. During the tempering
