Notes:
It is well know that Ni-5at.% W(Ni5W) and Ni-9.3at.% W(Ni9W) alloy substrates aretwo kinds of promising materials to be employed in coated conductors. The Ni5W substrate is veryeasy to produce cube texture, while the Ni9W alloy has a lower magnetic property and higherstrength. However, the pure cube texture are not capable to be obtained in Ni9W alloy. In this work,the preparation and texture development in both Ni5W and Ni9W alloy substrates have beenreported. Highly biaxial textured Ni5W substrate was fabricated by cold rolling, followed by threedifferent annealing routes. The texture analysis indicated that a sharp cube texture was formed afterannealing at a wide temperature range of 800-1100°C in as rolled Ni5W substrate. The high qualityof cube orientation was obtained after a two step annealing (TSA) with farthing twin boundariesanalyzed by EBSD. Furthermore, in order to obtain a pure cube texture in Ni9W alloy substrate, atypical rolling process was performed and the deformation texture was optimized in thesesubstrates. The designed deformation texture components were obtained in Ni9W alloy whenpre-heating the ingot at 250 °C before performing a cold rolling, which shows a possibility to formcube texture in Ni9W alloy substrate after annealing
