Definition: A eutectoid reaction is a three-phase reaction by which, on cooling, a solid transforms into two other solid phases at the same time. If the bottom of a single-phase solid field closes (and provided the adjacent two-phase fields are solid also), it does so with a eutectoid point. The eutectoid (eutectic-like) reaction is similar ...

WebA proeutectoid constituent is defined here as the first diffusional product to form from austenite upon cooling. The purpose of this chapter is to provide an updated, detailed description of the morphology and crystallography proeutectoid constituents, ferrite and cementite (mainly in slowly cooled or isothermally transformed steels).
WebMar 16, 2024 · At 779C, the eutectic, the entire sample would be pure β phase right there at the point on the Ag solidus line. Dropping below that means nucleating the α copper phase, taking some of the silver with it. You go from one phase to two - the amount of phase one must decrease. Trust the phase diagram, and wrap your understanding around it.
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.
