Eutectoid meaning
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). WebWhen of eutectoid composition, it is called " hardenite." The cementite which has thus far been forming may be called " pro- eutectoid " cementite, because it forms before the …

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. WebThe definition of eutectoidin the dictionaryis a mixture of substances similar to a eutectic, but forming two or three constituents from a solid instead of from a melt.

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.
