Abstract

1137427 Super-conducting alloys CENTRAL ELECTRICITY GENERATING BOARD 18 Aug 1967 [4 Aug 1966] 35023/66 Headings HIA A5 and A4D Binary super-conducting alloys comprise lead alloyed with 40-70 atomic % T1, 50-70 atomic % In, 0À8-10 atomic % Na or Bi in the range 15-21 atomic % or 29-42 atomic % and contain finely divided particles of oxide(s) of one or both of the alloying elements. The alloys are made by atomizing the alloy melt in an oxidizing atmosphere, optionally ball milling the powder in an oxidizing atmosphere to allow the oxidation to continue, and compacting the powder with mechanical working to break up the oxide layers, e.g. by extrusion. The compact may be further worked by swageing or re-extrusion. The alloys may be used in cables or iron-cored electromagnets.
