The temperature (in °C) of eutectoid reaction in the iron-carbon phase diagram is?
Eutectoid reaction:- A chemical reaction in which, during the cooling of a metal, one solid phase yields two different solid phases.
The temperature of the eutectoid reaction in the iron-carbon phase diagram is 723°C.
In the Fe-C system, there is a eutectoid point at approximately 0.8wt% C, 723°C.
The phase just above the eutectoid temperature for plain carbon steels is known as austenite or gamma.
