EFFECTS of DUAL DOPING OF C AND TiC NANOPARTICLES ON SUPERCONDUCTING PROPERTIES OF Fe-SHEATHED MgB2 TAPES

Description

Fe-sheathed MgB2 wires doped with C and TiC nanoparticles in the formula MgB2-xCx+yTiC(x = 0, 0.05, 0.1, 0.15, 0.2, and y = 0, 2.5 wt.%, 5 wt.%) were investigated. X-ray diffraction patterns indicate that the core materials in the wires contain small amount of Fe2B and MgO impurity phases, and the peaks shift with the variation of doping amount. It is found that the critical temperature Tc decreases with the increase of doping amount. Strong in-field current carrying capability enhancement was observed on MgB1.95C0.05+2.5 wt.% TiC.
