Abstract

The invention discloses a preparation method of an Nb3AL superconducting wire split conductor precursor. The preparation method comprises the following steps: preparing a complex bar, preparing an Nb3AL superconducting wire single core precursor and preparing an Nb3AL superconducting wire split conductor precursor. The preparation method of the Nb3AL superconducting wire split conductor precursor solves the problem that an existing preparation method has rigor requirements on manufacturing equipment and hardly removes the oxide layer on the surfaces of AL particles, and meanwhile a manufactured Nb3AL superconducting wire split conductor precursor is even in ingredients and good in performance, effectively reduces cost and is beneficial for mass production.

Description

technical field [0001] The invention belongs to the technical field of preparation of superconducting materials, in particular to a kind of Nb 3 A method for preparing an Al superconducting wire multi-core wire precursor. Background technique [0002] Among many practical superconducting materials, NbTi alloy and Nb 3 A15 structure intermetallic compounds such as Sn have been widely developed and applied, among which NbTi and Nb 3 Sn has been commercially applied, but with the continuous improvement of large-scale scientific research and commercial application requirements, Nb 3 Sn (4.2K, Hc 2 =22T~26T) performance has gradually failed to meet the demand. As a type of A15 intermetallic compound, Nb 3 Al superconducting materials have higher critical magnetic field and critical current density, and Nb 3 The research on the stress and strain relationship of Al shows that this material has very good strain resistance and good radiation sensitivity. 3 Ideal material for S...
