- In this paper the results of critical current measurements for $MgB_2$ wires and tapes in iron sheath with and without nano-SiC doping are presented. We focus on power-in-tube processing technique, using both in situ and ex situ methods. In situ $MgB_2$ wires and tapes were fabricated from $MgH_2$ and B or Mg and B powders. The methods such as hydrostatic extrusion and rolling were used. The samples were annealed under high Ar gas pressure (hot isostatic pressing) at 750°C and 1.0 GPa for 40 min. It was found that critical current of $MgB_2$/Fe superconducting wire or tape with nano-SiC dopant increased in higher magnetic field values in comparison to pure $MgB_2$. A significant difference of $J_c$ in tapes made by in situ way from $MgH_2$ and Mg were found.
