摘　　要：对于高钨含量的镍钨合金基带而言，难以通过传统的大变形量冷轧及再结晶退火得到强立方织构，为了提高Ni-9at．％W（Ni9W）合金基带再结晶立方织构的含量，本文优化了坯锭轧制及再结晶退火工艺。实验发现，在大变形量冷轧期间结合三次中间回复退火工艺可以提高轧制Ni～9at．％W合金基带中Copper和S型织构的含量，最后通过优化再结晶退火工艺，在1200℃保温2h的再结晶退火工艺下得到了立方织构含量为45．6％（≤10°）的Ni-9at．％W合金基带。It is very difficult to obtain sharp cube texture by heavy cold rolling and recrystallization annealing for NiW alloy substrates with a high W content. The rolling and recrystallization annealing technological parameter were optimized to improve the content of cube texture in Ni-9at. %W（Ni9W） alloy tapes. The content of C orientation and S type texture were improved by three recovery annealing cycles during the heavy cold rolled. The cube texture content in Ni-9at. %W alloy substrates reached 45.6% （410%） which was obtained by optimized recrystallization annealing at 1 200℃ for 2 h.
