Chapter 12, Problem 12.51P

Interpretation Introduction

Interpretation:

The Eutectoid reaction in FeFe ${}_3$ C system needs to be determined.

Concept Introduction:

A eutectoid reaction is defined as a three-phase reaction where the cooling process is done on a solid that transforms into other two solid phases at the same time.

The phase diagram consists of the eutectoid point that indicates the location at which 3 solid phases co-exist. In eutectoid reaction, the austenite transforms into a phase mixture of ferrite and cementite.
