摘要:

It has been observed that in the external diffusion process for producing Nb3Sn‐Cu superconducting wire, dewetting of the Sn layer occurs for layer thicknesses on the order of 6 &mgr;m and larger. A mechanism for this dewetting is proposed and it is demonstrated that the problem may be eliminated by formation of an oxide skin on the outer surface of the Sn layer.
