Abstract
Different constructions of magnesium diboride composites superconductors are presented. Magnesium powder prepared by the melt pulverization and boron powder as well have been used as initial materials in frames of "powder-in-tube" method to producing of various conductors design. Mono-filamentary and multifilamentary wires (1.0-2.0 mm in outer diameter and up to 100 m in length) in different metallic sheathes (Fe, Ni, Fe-Cu, stainless steel) were made by extrusion and drawing. The results of metallography investigations and transport measurements for the conductors and as well as for dummy coil are described.
