The microstructure of the MgB 2 wires with hydrocarbon, pyrene (C16H10) addition has been investigated by transmission electron microscopy (TEM) equipped with energy-dispersive X-ray spectroscopy (EDX). In our study, MgB 2 wires have been fabricated through powder-in-tube (PIT) process using pure Fe as sheath material and sintered at 600°C ~800°C for 30min to 4 hrs under high purity argon gas. TEM and EDS analyses were conducted on the specimens prepared by tripod polishing and ion milling method. The structural features such as second phases, interface and defects were investigated by electron microscopy.
