Nb/sub 3/Pt has been disordered by rapid splat quenching, which results in the superconducting critical temperature falling from 11K to below 7K. The kinetics of reordering, as evidence by the recovery of T/sub c/, were followed by isothermal and isochronal anneals. The results were analyzed according to Welch's model of reordering in A15 compounds and were found to follow 2nd order kinetics, as had been assumed in an earlier study of recovery in several neutron-irradiated A15 compounds. The activation energy for the reordering process is 3.5 +- 0.2eV. These results will be compared to those on the recovery of samples of Nb/sub 3/Pt irradiated to a dose of 7.5 x 10/sup 18/nvt fast (E > 1MeV) neutrons with a T/sub c/ = 6.15K. The implications of the nature of radiation damage in A15 compounds is discussed.
