Standart ve toz dahili magnezyum difüzyon teknikleriyle yapılan süperiletken mgb2 tel numunelerin mekanik deformasyon süreçlerinin mikro-sertlik testleri ile değerlendirilmesi

This research aims to investigate the mechanism of superconductivity and the production of MgB2 wires. The generation of high magnetic fields in practical applications requires long, homogeneous superconducting MgB2 wires. Various techniques, including the powder-in-tube (PIT) method and internal magnesium diffusion (IMD) technique, are employed to obtain superconducting wires. This study specifically focuses on the PIT method and IMD technique to create the MgB2 phase. The effect of hardness will be examined using HV tests, as the hardness of the constituents of the composite MgB2 wire is modified during the cold drawing process. The cross sections of the wire samples will be analyzed to determine if the regions of boron, magnesium and iron exhibit different HV results between the Standard and Powder IMD methods. This research aims to relate these findings with the mechanical behavior, superconducting properties, structure and microstructure of MgB2, whether the microhardness values do or do not differ.
