摘 要：采用真空感应熔炼方法制备一种无磁性且表面具有锐利立方织构的Ni-12%V(Ni12V，摩尔分数)金属合金基带，并对其性能进行表征。通过不同的轧制工艺研究大变形量冷轧前热轧处理对初始坯锭形变织构的影响。结果表明：经大变形量冷轧后基带表面形成了高层错能材料所具有的铜型形变织构，通过优化的再结晶工艺获得立方织构含量为97.2%(＜10°)的Ni12V合金基带，小于10°的小角度晶界含量占总晶界长度的80.8%。先热轧再冷轧有利于改善立方织构的形成，也为进一步优化其它Ni基合金基带提供了依据。
Abstract: A non-magnetic and high cube textured Ni-12%V(Ni12V, mole fraction) alloy substrate was developed by melting method. The fabrication processes of this tape and its essential characterizations were presented. The influence of hot rolling process before the large deformation on deformation texture of initial ingots was investigated by rolling technology. The results show that, after the optimized recrystallization annealing method, the cube texture content (＜10°) as high as 97.2% and the fraction of small angle (＜10°) grain boundaries as high as 80.8% are obtained in the Ni12V tape. The hot rolling before cold rolling is effective to improve the cube texture content, which is expected to provide a theoretical basis for fabricating other nickel-based alloy substrates.
