Chapter 11, Problem 11.14P

Interpretation Introduction

(a)

Interpretation:

Whether the intermetallic compound is present in the system or not needs to be determined.

Concept introduction:

The intermetallic compound is a crystal type structure which is mode by definite composition and proportion of two or more metallic elements to form a single metallic element. The intermetallic compound is not composed of variable composition this property makes the element different from others. Most of the alloys do not show solubility when the amount of solute element is more in the second phase, also appear apart from the primary solution.

Interpretation Introduction

(b)

Interpretation:

The temperature and three-phase reaction if any need to be determined.

Concept introduction:

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