| Outline of Final Research Achievements |
High tensile strength and high electrical conductivity Cu-Ti alloy wire has been developed to produce magnetic fields of 100 T using a non-destructive pulse magnet. From a vacuum melted ingot with composition of Cu-3.2wt%Ti, Cu-Ti wire with a cross section of 2mm×3mm has been obtained by a cold draw bench. Moreover, in order to recover fracture toughness and electrical conductivity, additional 2 stages heat treatments using a salt bath were applied to the wire. As a result, specifications of Vickers hardness Hv310 and the conductivity of 17%IACS have been achieved. The hardness is higher than that of a standard Cu-Ag alloy wire for practical use. Utility of the new Cu-Ti alloy wire will be examined by forming a pulse magnet coil.
