Patent ID: 10622537

Abstract:
A method for producing a semifinished product for a superconducting wire is provided herein. The semifinished product includes at least one NbTi-containing structure, such as a NbTi-containing rod structure. The NbTi-containing structure may be produced in layers by selective laser melting or selective electron beam melting of a powder that contains Nb and Ti. In the production of at least some layers of the NbTi-containing structure, during the production of an irradiated area provided for a material deposition of a respective layer, at least one process parameter of the selective laser melting or electron beam melting is varied in one or a plurality of first zones of the irradiated area as compared to one or a plurality of second zones of the irradiated area. The present techniques simplify introduction of artificial pinning centers into the NbTi-material of a superconducting wire or a semifinished product for such a superconducting wire.
