چکیده انگلیسی
A modified in situ PIT process, which included a short time pre-annealing and intermediate drawing step in the conventional in situ PIT process, was employed to fabricate thin round MgB2/Fe wires from MgH2 and B powders. The pores and cracks resulted from the MgH2 decomposition during the pre-annealing were effectively eliminated by the intermediate drawing step, which subsequently increased the core density and Jc property of final heat treated wires. A higher reduction rate after the pre-annealing led to a larger enhancement in Jc within this study. The reproducibility of our new process on the Jc improvement in MgB2 wires was confirmed in two series of wires doped with 5Â mol% or 10Â mol% nano-SiC particles separately.
