Thin,　reinforced　and　biaxially　textured　Ni5W/Ni12W/Ni5W　composite　substrate　for　coated　conductor　applications　has　been　fabricated　by　traditional　powder　metallurgy　method　using　the　sparking　plasma　sintering　(SPS)　technology,　followed　by　cold　rolling　and　annealing.　In-situ　EBSD　strain-stress　analysis　shows　that　the　yield　stress　(delta(0.2))　can　reach　240MPa.　The　high　quality　of　cubic　texture　and　boundaries　of　low　misorientation　angle　were　stable　until　elongations　as　high　as　2%.　Meanwhile,　the　cubic　grain　fractions　on　surfaces　of　top　Ni5W　layer　of　the　composite　tapes　are　98.3%,　99.5%　and　99.8%,　respectively,　corresponding　to　be　annealed　at　1250　degrees　C　for　60min,　120min　and　180min,　indicating　the　cube　texture　can　successfully　sustain　after　severe　treatment　condition.
