An interatomic potential that reasonably describes the properties of A15 Nb 3 Sn was newly developed and then used in atomistic simulations to investigate the detailed diffusion mechanism in the Nb 3 Sn compound. For volume diffusion in Nb 3 Sn, the formation of Sn Nb anti-site defect is rate determining while its movement through Nb …

2.1 Nb 3 Sn Development from the 1960s to the 1970s. The very first commercial Nb 3 Sn composite conductor, which was used for accelerator magnet models in the period from the 1960s to the 1970s, was in the form of a flexible tape (also called a ribbon). A schematic of a Nb 3 Sn ribbon is shown in Fig. 2.1. Fig. 2.1.
