摘要：

The results of investigations of first 500 kg Nb3Sn bronze strand are presented. This batch of strands was meant for the production of 100 m of Toroidal Field Conductor in the frame of fulfillment the Phase II of Procurement Arrangement between Russian Domestic Agency and International Organization ITER. In order to provide the industrial-scale production of strands design documentation and all necessary quality assurance documents were developed. The developed industrial technology of Nb3Sn strand production was applied in Joint Stock Company << Chepetsky Mechanical Plant >> (JSC << ChMP >>). Strands were produced in JSC << ChMP >> from final billets with diameter of 203 mm. The microstructure investigations of produced strands were performed before and after diffusion annealing by optical microscopy, X-ray microprobe analysis. Mechanical properties of annealed Nb3Sn strands were investigated. Current-carrying capability of Nb3Sn strands at 12 T, 4.22 K were studied. It was shown, that all produced strands met all the requirements, in particular I-c was from 202 to 220 A; hysteresis losses were from 165 to 194 mJ/cm(3) (+/- 3 T).
