摘要：

A　tri-layer　composite　alloy　ingot　was　fabricated　by　hot　isostatic　presses　(HIP)　method,　in　which　the　outer　layer　is　Ni-5%W　(Ni5W,　mole　fraction)　alloy　and　the　inner　layer　is　Ni-12%W　(Ni12W,　mole　fraction)　alloy.　The　composite　ingot　was　cold-rolled　using　the　process　of　rolling　assisted　biaxially　textured　substrate　(RABiTSTM)　technology　and　annealed　to　obtain　the　Ni5W/Ni12W/Ni5W　composite　substrate　with　high　cube　texture.　The　cold　rolling　and　the　recrystallization　textures　on　the　surface　of　the　as-obtained　composite　substrate　were　studied　systematically　by　X-ray　and　EBSD　measurements.　The　results　show　that　a　strong　deformation　copper-type　texture　is　obtained　in　the　cold　rolled　composite　substrate,　and　a　sharp　cube　texture　is　formed　on　the　surface　of　Ni5W/Ni12W/Ni5W　composite　substrate　after　a　recrystallization　annealing　process.　The　percentage　of　the　cube　orientated　grain　within　a　misorientation　angle　of　10°　is　as　high　as　99.1%,　which　is　in　the　same　level　as　that　of　the　commercial　Ni5W　tape.
