2- Ferrous alloys are most important and widely used in comparison to any other metals.
3- Metals of BCC crystal structure are denser than metals of FCC structure.
4- Hypo-eutectoid steels fully annealed by heating to about 30°C above the upper critical temperature. X A3
5- The full martensite microstructure can be obtained by cooling the steels with any cooling rate.
6- There is a large volume expansion when martensite forms from austenite.,
