摘要：

The　cube　textured　Ni-7%W　substrates　were　prepared　by　spark　plasma　sintered　(SPS)　ingot,　followed　by　rolling-assisted　biaxially　textured　substrate　(RABiTS)　processing.　The　grain　orientation　data　and　the　grain　boundaries　information　of　the　Ni-7%W(Ni7W)　substrate　were　collected　by　electron　backscatter　diffractometry　(EBSD).　The　texture　of　the　Ni7W　substrate　was　analyzed.　The　high　quality　of　EBSD　image　is　observed　on　the　sample　surface　after　annealing　process　without　polishing.　The　Ni7W　substrate　forms　a　sharp　cube　texture,　and　the　mass　fraction　and　length　fraction　of　the　cube　texture　grains　in　the　Ni7W　substrate　reach　99.4%　and　93.6%,　respectively,　within　tolerance　angle　smaller　than　10°.
