One　of　the　main　challenges　for　coated　conductor　applications　is　to　produce　sharp　cubic　textured　alloy　substrates　with　high　strength　and　low　magnetism.　At　present,　the　traditional　industrialization　Ni5at%W　(Ni5W)　alloy　substrates　have　been　large　into　production.　However,　the　formation　mechanism　of　recrystallization　texture　is　still　not　investigated　definitely.　In　this　work,　the　cube　textured　Ni5W　substrates　with　similar　to　99%　cold-rolling,　starting　from　advanced　smelting　casting　ingots　followed　by　Rolling　Assisted　Biaxial　Textured　Substrate　(RABiTS),　have　been　prepared.　The　evolution　of　deformation　and　recrystallization　textures　in　the　Ni5W　tape　has　been　investigated　by　Electron　Back　Scattering　Diffraction　(EBSD).　Results　show　that　the　cold-rolled　texture　is　a　typical　Cu-type　deformation　texture　on　a　global　scale.　Due　to　the　nucleation　advantage,　cube　gains　are　easily　produced　on　the　surface　of　the　Ni5W　tapes　at　the　early　stages　of　recrystallization　and　there　is　a　nucleation　gradient　along　the　thickness　of　the　tapes.　The　formation　of　cube　texture　in　Ni5W　alloy　appears　primarily　during　the　size　advantage　and　preferential　growth　of　cube　grains　has　been　discussed.
