A vacancy generation kinetics from dislocations has been studied by a pulse-heating method and residual resistance measurement on zone refiend aluminum. From the generation curve of vacancies, the migration energy of mono-vacancy, E m , was determined as 0.66±0.05 eV in the temperature range from 310 to 400°C. Furthermore, it was concluded that the temperature dependence of E m is small in aluminum.
