The　cube　textured　Ni-7at%W(Ni7W)　substrates　were　prepared　starting　from　spark　plasma　sintered　ingot,　followed　by　Rolling-Assisted　Biaxially　Textured　Substrate　(RABiTS)　processing.　According　to　the　EBSD　and　XRD　analyses　of　the　fully　annealed　tape,　the　cube　grain　content　of　the　tape　reaches　as　high　as　99.4%　within　a　tolerance　angle　of　less　than　10　degrees　and　the　grain　boundary　length　content　is　93.6%　within　a　tolerance　angle　of　less　than　10　degrees,　while　the　FWHM　values　of　the　in-plane　and　out-of-plane　orientations　are　about　6.32　degrees　by　(111)　Phi-scan　and　5.4　degrees　by　(200)　omega-scan,　respectively,　indicating　that　the　tapes　have　sharp　cube　texture.　The　Ni7W　substrate　has　a　uniform　grain　size　and　high　quality　of　cube　texture.　The　La2Zr2O7　(LZO)　buffer　layer　fabricated　on　Ni7W　substrates　shows　that　the　epitaxially　textured　LZO　buffer　layer　could　be　formed　on　the　as-obtained　Ni7W　substrate.　The　FWHM　values　of　(222)　phi-scan　and　(400)　omega-scan　are　7.57　degrees　and　5.73　degrees,　respectively.
