Resistivity measurements at 300 K show that an annealed metal single crystal has amonovacancy concentration CV = 10-9. When the same crystal is quenched from a hightemperature, the measurements indicate CV = 2x10-3. Calculate the temperature of thequench [Take Hf = 51.4 kJ/mol and R = 8.314 J/mol.K]. State any assumption involved. (5)(b) Explain why the esistivity of a metal is expected to be found more at room temperature after quenching. Hint: Use Matthiessen’s rule (find out by self-studying and cite thesource.)

write a summary of each of the techniques for measuring vacancyconcentrations, noted therein. (1) Measurements of the quenched-in residual electricalresistivity of aluminium rapidly cooled from temperatures be-low about 800 K with initial quenching rates of 2 × 106 K s−1give the enthalpy of formation of monovacancies H F1V =(0.65 ± 0.01) eV.(2) Comparison of the quenching data with high-temperature differential-dilatometry data gives the monova-cancy formation entropy SF1V = (0.76 ± 0.4)kB (kB =Boltzmann’s constant) and the low-temperature resistivity perunit concentration of vacancies ρ1V = (1.9 ± 0.1) μm.(3) The binding enthalpy of divacancies in Al is H B2V =(0.17 5 ± 0.02 5) eV. This is in agreement with earlier ex-perimental determinations by Doyama and Koehler 48) and byLevy et al. 49, 50) but in marked contrast to the claim of Carlinget al., 23) based on computations with the generalized gradi-ent approximation, that in Al H B2V is zero or even negativeand therefore the…
