摘要：

The nature of the defect or defect complexes produced in superconducting compound Nb3Sn by high energy (E ≧ 1 MeV) neutron irradiation is studied by transmission electron microscopy. The damage appears to be primarily in the form of highly disordered regions of size 2 to 6 nm in a much less disordered matrix. Both the ordered matrix and the disordered regions essentially retain A15 structure. Using superlattice and fundamental reflections it is shown that the disordered regions contain a high density of antisite defects as well as associated strain fields.
