Abstract

The fabrication of bulk, stoichiometric MgB2wires is a challenge because of the difficulties associated with the volatility and reactivity of magnesium and the brittleness of MgB2. Metal-clad processing of MgB2is a convenient, practical method of overcoming these problems. With such a fabrication approach, iron-clad MgB2superconductor wires exhibiting desirable characteristics with the transport Jcof ∼105 A/cm2at 4.2K have been obtained. In this paper, understanding of the composite wire structures, effect of processing parameters, grain boundary characteristics, and critical current bahavior of the MgB2wires will be described.
