摘要
A method for producing a Sn based alloy (15) comprisinga) a metal matrix of a metal matrix material, wherein the metal matrix material comprises Sn,b) and inclusions of a compound material, further referred to as compound inclusions, wherein the compound material contains- one element or a combination of elements of the group Ti, V, Zr, Hf, further referred to as dopant,- and one or a plurality of other elements, in particular Sn, Cu and/or Nb,is characterized in that particles of the metal matrix material, further referred to as matrix particles, are mixed with particles of the compound material, further referred to as compound particles,and that the matrix particles and the compound particles are compacted during and/or after their mixing. By the inventive method, a Sn based alloy containing finer compound inclusion of a dopant can be prepared, in order to produce Nb3Sn superconductor material with a superior current carrying capacity.
