摘要：

An important part of the SSC Phase I and II strand R&D programs was an extensive sampling scheme that covered the entire fabrication process of the strand. Samples were sent to the UW where complete microstructural and physical property analyses could be performed. In addition, sufficient extruded pre-heat treatment multifilamentary material was provided to the UW so that parallel processing to strand could be performed. In Phase I material it was found that the 2 vol.% Nb diffusion barrier thickness was insufficient to prevent extrinsic limitation of J, This contrasted with the Phase II strand which incorporated 4% barriers and showed intrinsic behavior. The intrinsic nature of the Phase H conductor has made it possible to probe the basic microstructure property relationships of the strand and provide insight into improvements in future processing.
