Abstract :
Ti-sheathed MgB2 wires doped with different amount of TiC nanoparticles were investigated. X-ray diffraction pattern suggested the existence of TiC0.59 phase and carbon incorporation into MgB2 lattice to form Mg(B1-xCx)2. Strong enhancement of in-field current carrying capability was observed on 2.5% TiC doped sample. The temperature effect was also studied. It was found that 850degC was the optimized annealing temperature.
