The　texture　evolution　of　Ni5W　out　layer　in　the　composite　tapes　with　multi-layer　structure　was　investigated　by　the　means　of　four　circle　X-ray　diffraction　and　EBSD　techniques.　Results　show　that　both　the　gradient　distribution　of　deformation　texture　and　the　diffusion　between　each　layer　dominate　the　texture　development　of　the　Ni5W　out　layer　in　the　composite　tapes.　This　explanation　is　useful　in　view　of　discussing　the　relationships　governing　the　texture　formation　of　each　layer　in　composite　tapes.
