In　this　work,　the　effect　of　cold　rolling　and　heat　treatment　upon　the　microstructure　and　texture　of　the　surface　layer　and　cross-section　of　Ni5W　alloy　substrate　was　analyzed　via　the　EBSD　technique.　A　typical　copper　deformation　texture　was　shown　by　the　cold-rolled　Ni5W　alloy　substrate.　The　cube-oriented　nuclei　were　attributed　to　the　rolling　direction-transverse　direction　(RD-TD)　plane　due　to　the　presence　of　copper　and　S　rolling　textures.　Typical　large-shape　cold-rolled　microstructure　was　presented　by　the　RD-ND　surface　in　the　cube-oriented　area.　During　the　recrystallization　process,　the　cube-oriented　grains　did　not　have　a　nucleation　quantity　advantage,　but　they　did　have　an　obvious　growth　advantage　compared　with　other　orientation　grains.　They　can　form　a　strong　cube　texture　by　absorbing　the　random　orientation　and　rolling　orientation　through　the　migration　of　large-angle　grain　boundaries.
