The MgB2/Fe wires were cold drawn to 0.81 mm diameter. The structural investigation of superconducting MgB2 layers was completed using X-ray diffraction and scanning electron microscopy. There are no traces of unreacted magnesium in the central region after Mg/B reaction. The use of magnesium powder increases the reaction rate and provides rapid Mg diffusion. The Mg powder method is also effective in reducing boron-rich regions in MgB2 IMD wires.eninfo:eu-repo/semantics/closedAccessSuperconductorInternal Mg DiffusionMgB2 WireMg PowderSemi-crystalline BoronArticle10.1016/j.physb.2020.4122775932-s2.0-85085731809Q2WOS:000563749000011Q3
