1) a) If the vacancy concentration in Cu is measured to be 10-5 at 1300K (near its melting point), what is Evf? (assume the pre-exponential factor is 1; ie, nv/N = exp (-Evf/kT)

b) What would be the concentration at 650 K?

2) Determine the largest size of an interstitial hole in FCC Fe. RFe = 0.124 nm.

Would a C atom sit in an interstitial or substitutional site (rC = 0.077 nm)?

3) When a nuclear reactor wall is irradiated, many vacancies and interstitials are created. The vacancies cluster together to form voids; what do you think happens to the interstitials?
