The order associated with the reaction kinetics was determined at temperatures appropriate for the various annealing peaks by fitting 2l.0 minute isothermal anneals to first or second order. The recovery of the silver and copper alloys showed remarkable similarity to pure silver and copper, but the gold alloy's recovery was markedly altered as compared to pure gold. Activation energies for the stage III defect in silver, copper and gold were found to be ,64, .71 and ,70ev respectively. The copper and silver alloys both had a small first order recovery stage near the low temperature side of the main stage III annealing peak. The main stage III peak obeyed second order kinetics in all cases. In the gold alloys the stage III recovery was composed of a main second order annealing peak with a small second order annealing peak on each side of the main peak. These annealing results have been fitted to the various models for the recovery of damage and some conclusions are drawn.
