Abstract:　The　cube　texture　evolution　of　Ni-5　at%W　alloy　deformed　up　to　a　very　high　strain　was　thoroughly　investigated　by　X-ray　diffraction　(XRD)　and　electron　back-scattered　diffraction　(EBSD)　during　the　process　of　deformation,　recrystallization　and　grain　growth.　A　typical　copper-type　rolling　texture,　mainly　consisting　of　components　of　S,　copper　and　brass　orientations,　is　obtained　after　heavy　cold　rolling.　The　fraction　of　rolling　texture　is　slightly　strengthened　during　recovery　and　then　strongly　reduced　during　recrystallization　process.　The　cube　texture　is　formed　by　consuming　the　rolling　texture　components　during　the　discontinuous　recrystallization　process.　The　cube　grains　have　a　size　advantage　with　respect　to　the　non-cube　grains.　A　strong　cube-textured　Ni5W　alloy　substrate　with　cube　texture　area　fraction　of　98.2　%　(<10°)　is　obtained　after　annealing　at　1050　°C　for　1　h.　The　full　width　half　maximum　(FWHM)　values　for　the　X-ray　(111)　φ-scan　and　the　(002)　ω-scan　of　this　substrate　are　5.84°　and　4.76°,　respectively.　Furthermore,　the　area　fraction　of　{001}　〈110〉　orientation　of　the　epitaxially　grown　La2Zr2O7　buffer　layer　is　97.1　%　(<10°),　and　the　FWHM　values　of　(111)　φ-scan　and　(002)　ω-scan　are　5.22°　and　5.00°,　respectively.　©　2016　The　Nonferrous　Metals　Society　of　China　and　Springer-Verlag　Berlin　Heidelberg
