Elastic Anisotropy in Multifilament $\hbox{Nb}_{3}\hbox{Sn}$ Superconducting Wires
2015
The elastic anisotropy caused by the texture in the Nb 3 Sn filaments of PIT and RRP wires has been calculated by averaging the estimates of Voigt and Reuss, using published Nb 3 Sn single crystal elastic constants and the Nb 3 Sn grain orientation distribution determined in both wire types by Electron Backscatter Diffraction. At ambient temperature the calculated Nb 3 Sn E-moduli in axial direction in the PIT and the RRP wire are 130 GPa and 140 GPa, respectively. The calculated E-moduli are compared with tensile test results obtained for the corresponding wires and extracted filament bundles.
