Unveiling the nucleation and growth of Zr oxide precipitates of internally oxidized Nb3Sn superconductors

Jaeyel Lee, Zugang Mao, Dieter Isheim +2

We report on atomic-scale analyses of nucleation and growth of Zr oxide precipitates and the microstructural evolution of internally oxidized Nb3Sn wires for high-field superconduc…
