Eutectic reaction is a reaction wherein, upon cooling, … WebProeutectoid signifies is a phase that forms (on cooling) before the eutectoid austenite decomposes. It has a parallel with primary solids in that it is the first phase to solidify out of the austenite phase. Thus, if the steel is hypoeutectoid it will produce proeutectoid ferrite and if it iRead more

WebEutectoid Reaction. A chemical reaction in which, during the cooling of a metal, one solid phase yields two different solid phases. In the iron-carbon phase diagram this reaction occurs as austenite drops below the eutectoid point, and results in austenite transforming into ferrite and cementite, in the form of pearlite.

A eutectic system or eutectic mixture is a homogeneous mixture that has a melting point lower than those of the constituents. The lowest possible melting point over all of the mixing ratios of the constituents is called the eutectic temperature. On a phase diagram, the eutectic temperature is seen as the eutectic point (see plot on the right).
