(a)
The density of FCC iron.
Answer to Problem 2.6P
The density of FCC iron is
Explanation of Solution
Given:
The density of BCC iron at room temperature is listed as
At temperature above
The lattice parameter is
Formula used:
Write the expression to find the number of atoms per unit volume.
Here,
Write the formula to find the density of silver.
Here,
Calculation:
Gama phase iron has theFace Centered Cubic (FCC) structure with
Substitute
The molecular weight of silver is
Avogadro’s number is
Substitute
Conclusion:
Therefore, the density of FCC iron is
(b)
The difference in the density of the FCC phase relative to the BCC phase of iron.
Answer to Problem 2.6P
The density of the obtained FCC phase is higher than the BCC phase of iron.
Explanation of Solution
Calculation:
The obtained density of FCC iron is
Compare the obtained density of FCC iron at
Conclusion:
Therefore, the density of the obtainedFCC phase is higherthan the BCC phaseof iron.
