N2 - Magnetic Resonance Imaging (MRI) is a medical device that relies on magnetic fields generated by superconducting wires to detect brain tumors. To generate magnetic fields, the medical device employs Niobium-based superconductor. This superconductor has several disadvantages, such as low critical temperature, limited raw material resources, and expensive raw material prices. Magnesium diboride (MgB2) has a critical temperature of 39 K, allowing it to be a suitable replacement for Niobium-based superconductors. In this research, a comprehensive analysis was conducted on the effect of adding nano-SiC on the structure and electrical transport properties of MgB2 superconducting wire. An investigation into the mechanical properties of the wire sheath was also done to determine if the wire can proceed to the next process. Using the Powder in Tube (PIT) method, followed by a cold deformation scheme, MgB2-based monofilament wire was manufactured. The findings of the X-Ray Diffraction (XRD) test confirm that the lattice constant -a of the MgB2 hexagonal phase decreases with increasing nano-SiC content addition. This lattice distortion causes the critical temperature of the MgB2 superconducting phase to drop from 37.99 K to 36.94 K. The addition of 5 wt% nano-SiC at 290 K causes the material to become more insulating, as evidenced by an increase in resistivity value from 256.18 µΩ.cm to 411.61 µΩ.cm. The mechanical characteristics of sheath demonstrate recovery following a cold reduction of around 56.25% and subsequent heating at 1073 K. The ultimate tensile strength and average hardness value are 585 MPa and 215.30 HV, respectively.
