Unformatted text preview: at its melting point, T=2800 ° C. Its energy for the formation of one pair of defect is 6 eV. Assume n/N = exp (-Q/2kT). 1 eV = 1.602x10-19 J, k=13.81x10-24 J/K= 86.20x10-6 eV/K n/N = exp [- 6/(2x86.20 x10-6 x 3073)]= exp (-11.325)=1.2x10-5 3. A dislocation loop shown below was observed.
