摘要：

Ni-W　alloys　are　the　most　excellent　substrate　materials　for　high　temperature　superconducting　YBa2Cu3O7-δ.　In　order　to　obtain　high　current　density,　strong　cube　texture　must　be　formed　in　Ni-W　substrates.　Ni-W　alloys　were　fabricated　by　spark　plasma　sintering　system.　The　Ni-W　substrates　were　obtained　by　the　method　of　rolling　assisted　biaxially　textured　substrates　(RABITS).　Cold　rolling　and　recrystallisation　textures　were　studied　systematically　by　X-ray.　The　results　show　that　the　heavier　cold　rolling　reduction,　higher　temperature　of　annealing　and　a　two-step　recrystallisation　annealing　are　beneficial　to　forming　of　cube　texture　in　Ni-W　substrates.
