A three-phase reaction in which one solid phase transforms to two different solid phases.
1) An isothermal reversible reaction in which a solid solution on cooling is converted into two or more intimately mixed solids. The number of solids formed are the same number of components in the system. 2) An alloy having the same chemical composition indicated by the eutectoid point on a equilibrium diagram.
The product of the eutectoid transformation.
an equilibrium phase transformation in which a single phase solid transforms to two different solid phases on cooling through the invarient temperature
a single solid phase transforming to two different solid phases on cooling
A eutectoid system occurs when a single-phase solid transforms directly to a two-phase solid.
(1) An isothermal reversible reaction in which a solid solution is converted into two or more intimately mixed solids on cooling, the number of solids formed being the same as the number of components in the system. (2) An alloy having the composition indicated by the eutectoid point on an equilibrium diagram. (3) An alloy structure of intermixed solid constituents formed by a eutectoid reaction.
A mixture of two or more constituents which forms on cooling from a solid solution and transforms on heating at a constant minimum temperature. A eutectoid steel contains approximately 0.83% carbon.
