The kinetics of precipitation of vacancies in quenched gold were studied by calorimetry when stacking-fault tetrahedra were formed. The samples were quenched from 900C and annealed inside a conduction differential microcalorimeter. The continuous measurement of heat flow produced during this annealing allowed the kinetic relation between the processes of nucleation and growth of the tetrahedra to be studied. The migration energy monovacancies was evaluated during the nucleation stage (0.94eV). During the growth stage an activation energy of 0.74eV appeared, which was interpreted as being the sum of the migration energy of a divacancy (0.68eV) and the displacement energy of growth ledges (0.06eV).
