Abstract

The strain effects and mechanical properties in “in situ” processed Nb3Sn conductors have been investigated in relation to the parameters specifying the fabrication conditions. The effects of these parameters are discussed in order to provide a guide for the optimization of fabrication. The parameters are [1] Nb content in Cu-Nb alloy (25, 30 and 35 w%Nb), [2] total reduction ratio R.R. of cross-sectional area (R.R.=4700, 40000, and 250000), [3] presence/absence of Cu stabilizer with Ta barrier, and [4] heat treatment time (at 550 C for 1, 3.5, 7 and 14.2 day).
