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
Phase transition — This diagram shows the nomenclature for the different phase transitions. A phase transition is the transformation of a thermodynamic system from one phase or state of matter to another. A phase of a thermodynamic system and the states of matter… … 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

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

Quench — A quench refers to a rapid cooling. In polymer chemistry and materials science, quenching is used to prevent low temperature processes such as phase transformations from occurring by only providing a narrow window of time in which the reaction is … Wikipedia
Lamellar structure — Lamellar structures or microstructures are composed of fine, alternating layers of different materials in the form of lamellae. They are often observed in cases where a phase transformation front moves quickly, leaving behind two solid products,… … Wikipedia
