摘要：

Combining mechanical alloying and powder-in-tube processing is a promising way to obtain tapes with excellent properties. Taking advantage of the properties of nanocrystalline precursor powders, it was possible to obtain J(c) values of 10(4) A/cm(2) at 12.1 T and 4.2 K. Evidential substitution of carbon into the MgB2 changed the electron scattering and therefore raised the B-c2 up to 12 T at 10 K. Systematic investigation on the influence of the heat treatment showed that, although an interfering Fe2B reaction layer was formed, an excellent J(c) of 10(4) A/cm(2) at 14.3 T and 4.2 K was achieved.
