Abstract

The kinetics of Nb3Sn phase formation in commercial multifilamentary wires have been studied as a function of time and temperature using time-resolved, in situ neutron diffraction. This work shows that at higher temperatures the Nb3Sn phase forms in a fraction of the recommended annealing time. A temperature-independent Avrami exponent of n = 0.51 ± 0.01 was observed, indicating a diffusion-controlled growth mechanism, and a large apparent activation energy of Ea = 10 ± 1 eV is reported where the energies of nucleation and growth both contribute.
