eutectoid [yü′tek‚tȯid]
(metallurgy) A mixture of phases whose composition is determined by the eutectoid point in the solid region of an equilibrium diagram and whose constituents are formed by the eutectoid reaction. (physical chemistry) The point in an equilibrium diagram for a solid solution at which the solution on cooling is converted to a mixture of solids. Eutectoid a eutectic that forms when a solid solution cools. In a phase diagram, a eutectoid point corresponds to the equilibrium of a solid solution whose phases have dissociated; the number of phases is equal to the number of components. A eutectoid point is analogous to a eutectic point in the case of the solidification of a liquid solution. An example of a eutectoid is pearlite in steel. Want to thank TFD for its existence?

No references found | It is known that the Ferrite content of the Matrix depends on the Chemical Composition of Ductile Iron on the rate at which it is cooled through the Eutectoid Transformation range. [FIGURE 2 OMITTED] It also was found that microcarbide formation is controlled by: elements that control carbon diffusion rate between eutectic and eutectoid temperatures; shakeout temperature; and excess concentrations of carbide-forming elements. For gray iron castings, according to the foundry, a high cooling rate results in: * quick solidification with refined solidification structure; * higher carbon content in the austentite matrix, resulting in a high volume percent of carbide in the pearlite structure; * quick eutectoid phase transformation, resulting in a refined pearlite structure. |
