Quenching and Annealing of Zone-Refined Aluminum

Abstract
Detailed annealing studies have been done on quenched zone-refined aluminum. The research was undertaken to determine the migration energy of the divacancy EM2 and the binding energy of the divacancy B2 in pure aluminum. It was found that EM2=0.50±0.04 eV and B2=0.17±0.05 eV. Some discussion of the properties of larger vacancy clusters is given.
