Chapter 11, Problem 11.11P

Interpretation Introduction

(a)

Interpretation:

The present intermediate compound needs to be determined.

Concept Introduction:

Intermetallic compounds are crystal compoundsthatare composed a ofdefinite proportionof two or more metallic elements to form a single metallic element. They are not composed of variable proportions. The complete solubility is not shown by most of the alloys. The appearance of second phase can be seen when amount of solute is more than initial value.

Interpretation Introduction

(b)

Interpretation:

The solid solution in the system needs to be determined.

Concept Introduction:

Allotropes are two or more crystal structures of the same material. Allotropy is a behavior of metal that is exhibited by a chemical element which exists in different forms. In each allotrope, the atoms are bonded together in a different manner. Allotropy refers to a different element having the same phase or state of matter, the change of state between solid, liquid in themselves are not considered as allotropy.

Interpretation Introduction

(c)

Interpretation:

The three-phase reaction needs to be determined.

Concept Introduction:

Three-phase reaction is also termed as a eutectoid reaction . A three-phase system is a solid transformation into two other phases of solid at the same time In Eutectoid system, the liquid phase is replaced by the solid phase to the eutectic system. This phase involves the transmission of the solid phase into two other solid phases.
