Chapter 12, Problem 12.122AP

(a)

Interpretation Introduction

Interpretation: The given alloys fit the general size requirements for substitutional alloys is to be stated and the density of $\text{LiAl}$ is to be calculated.

Concept introduction: Substitutional alloys are the alloys that are similar in size and there is a exchange of atoms with other atoms, where some atoms that are producing the metallic crystals are exchange with the atoms of other constituent.

The density of the unit cell is defined as the mass of the unit cell divided by the volume of the unit cell.

$\text{Density}\text{of}\text{the}\text{unit}\text{cell}=\frac{\text{Mass}\text{of}\text{the}\text{unit}\text{cell}}{\text{Volume}\text{of}\text{the}\text{unit}\text{cell}}$

To determine: If the given alloys fit the general size requirements for substitutional alloys.

(b)

Interpretation Introduction

To determine: The density of $\text{LiAl}$.
