Ni8W　alloy　ingots　were　prepared　by　SPS　technic,　followed　by　homogenizing,　cold　rolling　and　recrystallization　annealing.　The　influence　of　ball　milling　on　cold　rolling　and　cube　texture　formation　of　Ni8W　alloy　substrates　was　investigated　during　the　course　of　preparation.　Finally,　high　quality　cube-textured　Ni8W　alloy　substrates　were　successfully　obtained　using　this　powder　metallurgy　process,　and　characterized　by　electron　backscatter　diffraction　technic.　It　indicated　that　the　cube　texture　fraction　was　as　high　as　90%　(＜10　degrees)　when　it　annealed　at　1350　degrees　C　for　2　h.
