Microstructure formation of steels during solidification

Steels solidify as solid solutions. The face-centered cubic lattice structure with the embedded carbon atom is called austenite. Introduction In principle, steels are binary systems consisting of the host element iron and the alloying element carbon with a maximum content of 2 % (above 2% carbon, the iron-carbon alloy is called cast iron!).

Microstructure of Ferrous Alloys

2001/1/10Martensite can be formed in alloys where the solute atoms occupy interstitial sites, such as carbon in iron, producing substantial hardening and a highly strained, brittle condition. However, in carbon-free alloys having high nickel contents, such as maraging steels, the solute atoms (Ni) can occupy substitutional sites, producing martensites that are soft and ductile.
