  • Abstract
    MgB2/Fe wire samples were prepared by using ball-milled 96% boron (B) powder with strong semi-crystalline phase. We observed samples that contained ball-milled 96% B in comparison with one made from as-supplied commercial 96% B, with the results showing a significant enhancement in the high field transport critical current density (J ct) due to small grain size and better reactivity. However, the inter-grain connectivity became worse, which could lead to poor J ct in low field and an increased level of disorder.
