Magnezyum diborür tellerin mikro yapisi ve gerilme analizi - microstructure and stress analysis of the magnesium diboride wires

MAGNEZYUM DIBORUR TELLERIN MIKRO YAPISI VE GERILME ANALIZI Bu calismada, isil islem prosesinin superiletken Magnezyum Diborur tellerin mikro yapisina ve olusan gerilme dagilimlarina etkisi incelenmektedir. Surekli Tup Bicimlendirme ve Doldurma (CTFF) prosesi ile farkli caplarda uretilen superiletken Bakir/Magnezyum Diborur tellerin mikro yapisi Taramali Elektrom Mikroskopu (SEM) ve Enerji Dagilim Spektroskopisi (EDS) kullanilarak karakterize edilmektedir ve gerilme dagilimi hesaplari analitik olarak hesaplanmistir. Bu calismada, Bakir/Magnezyum Diborur tellerin ara bolgesinde gerilme degerlerinin maksimum degerde oldugu gorulmektedir. MICROSTRUCTURE AND STRESS ANALYSIS OF THE MAGNESIUM DIBORIDE WIRES In this study, the effect of the annealing process on the microstructure and the stress distribution of the Magnesium Diboride wires were investigated. The presented microstructure properties of the Copper/Magnesium Diboride wires are characterized for the varous diameters fabricated by the Continuous Tube Forming and Filling (CTFF) by using Scanning Electron Microscopy (SEM) and Electron Dispersive Spectroscopy (EDS) and the stress distribution is calculated analytically. In this study, it is observed that values of stress components are maximum at the interface region of Copper/Magnesium Diboride wires.
