Question

Expert Solution

Step 1

Solution - There will be no change in density because at 25• C , the crystal structure of iron is BCC and at 200• C also the crystal structure is BCC . So there is no change in crystal structure due to change in temperature .

(a) Pure iron has a change in crystal structure from BCC to FCC when heating up above 912°C. If the atomic radius of an Fe atom is 0.124 nm, calculate the volumes of the FCC and BCC unit cells. (b)Recall that there are two atoms per BCC unit cell, and four atoms per FCC unit cell. With this information in mind, calculate the percent change in volume of a sample of pure Fe as it transforms from an FCC to a BCC structure upon cooling below 912°C. Specify if this percent change manifests as an increase or decrease in volume of the sample.
