According　to　the　requirement　of　applied　superconductivity　coating　for　the　texture　of　Ni5W　alloy　substrate,　the　influences　of　rolling　routes,　rolling　speed　and　rolling　lubrication　on　the　rolling　deformation　texture　and　the　recrystallization　cube　texture　of　Ni5W　alloy　substrate　were　analyzed.　The　results　showed　that　rolling　to-and-fro　avoided　the　production　of　other　rolling　directions　which　were　not　conducive　to　the　formation　of　recrystallization　cube　texture.　Thus　there　was　more　C-　and　S-　type　orientation,　which　were　beneficial　for　obtaining　sharp　recrystallization　cube　texture　through　annealing　process.　The　distributions　of　recrystallization　grain　boundary　for　rolling　process　with　and　without　lubrication　were　analyzed,　and　found　that　without　lubrication　rolling,　there　were　less　twin　grain　boundaries　and　grain　boundary　was　in　better　quality.　The　rolling　speed　of　5　m　·　min-1　was　the　best.　Corresponding　optimized　rolling　technology　was　put　forward,　which　provided　reference　for　texture　controlling　and　properties　optimizing　of　rolling　substrate.　Finally,　the　20　meters　long,　63　μm　thickness　tapes　with　~99%(>10°)　cubic　texture,　homogeneous　Ni5W　tapes　were　obtained　after　cold　rolling　and　annealing.
