Which of the following reaction does not exhibit mushy zone in Fe-C phase diagram?

Right Answer is:

Eutectic reaction

SOLUTION

A eutectic reaction is a three-phase reaction, by which, on cooling, a liquid transforms into two solid phases at the same time. It is a phase reaction, but a special one.

A mushy zone is where the melting or solidification actually begins and proceeds, accompanying which the latent heat absorbs or releases.
