Eutectic point — The melting point of a mixture of two or more solids (such as an alloy) depends on the relative proportions of its ingredients. A eutectic or eutectic mixture is a mixture at such proportions that the melting point is as low as possible, and that … Wikipedia
Austenite — (or gamma phase iron) is a metallic non magnetic solid solution of iron and an alloying element. In plain carbon steel, austenite exists above the critical eutectoid temperature of 1000 K (about 727 °C); other alloys of steel have different… … Wikipedia
Ferrite (iron) — Ferrite or alpha iron (α Fe) is a materials science term for iron, or a solid solution with iron as the main constituent, with a body centred cubic crystal structure. It is the component which gives steel and cast iron their magnetic properties,… … Wikipedia

Pearlite — is a two phased, lamellar (or layered) structure composed of alternating layers of alpha ferrite (88 wt%) and cementite (12%) that occurs in some steels and cast irons. It forms by a eutectoid reaction as austenite is slowly cooled below 727°C.… … Wikipedia
Ledeburite — In iron and steel metallurgy, ledeburite is the eutectic that results when some forms of molten steel solidify.It is named after the metallurgist Karl Heinrich Adolf Ledebur (1837–1916). He was the first professor of metallurgy at the… … Wikipedia
