Improvement of the current carrying capability of ex situ MgB2 wires by normal particle additions

Abstract:

A wide variety of powders, including Nb, Ti, Zr, Hf and W, metal oxides like Nb2O5, Ti2O5, V 2O5 and other compounds like SiC, SrCO3 and boron nitride, have all been used at the 10 wt% level as additions into commercial MgB2 powder for the fabrication of single-core, ex situ wires using groove and two-axial rolling deformation and final heat treatment at 950°C/0.5 h in Ar. Transport current measurements have shown that metal particle addition leads to an especially significant improvement in ...
