Chapter 12, Problem 12.109P

Interpretation Introduction

Interpretation:

When the temperature is lowered, the changes occur in the eutectic and eutectoid phase needs to be explained.

Concept Introduction:

Eutectic reaction as the name suggests a solid transformation into two other solid phases at the same time. Three-phase reaction is also termed as a eutectoid reaction. In a eutectoid system, a solid phase replaces the liquid phase this phase involves the transformation of solid-phase into two other solid phases.
