根据涂层超导应用对Ni5W合金基带织构的要求,分析研究了轧制方式、轧制工艺润滑、轧制速度等对Ni5W合金基带轧制形变织构及再结晶立方织构的影响,研究发现,往复轧制避免了不利于形成再结晶立方织构的其他冷轧取向的产生,进而在Ni5W合金基带中获得较多的C型和S型取向,利于退火过程中获得锐利的再结晶立方织构,对比分析了非润滑轧制和润滑轧制的再结晶晶界分布情况,发现非润滑轧制较润滑轧制产生的孪晶界含量少,且晶界质量比较高,并对3种不同轧制速度的轧制结果进行了分析,得出5 m.min-1为最佳的轧制速度。提出了相应的优化轧制工艺,为轧制基带的织构控制和性能优化提供参考,最终冷轧和退火后获得了长度为20 m,厚度为～63μm,立方织构含量达～99%(<10°),性能均匀的Ni5W合金基带,为Ni5W合金基带长带的产业化生产奠定了基础。
According to the requirement of coating superconducting on the texture of Ni5W alloy substrate, the influence of rolling mode, rolling process lubrication and rolling speed on the deformation and recrystallization cubic texture of Ni5W alloy base strip was studied. It has been found that the reciprocal rolling process avoids the occurrence of other cold-rolled orientations that are detrimental to the formation of recrystallized cubic texture and further the C-and S-type orientations in the Ni5W alloy base, favoring the sharp recrystallized cubic during annealing Texture and comparative analysis of non-lubrication rolling and lubrication of the recrystallization grain boundary distribution and found that non-lubrication rolling lubrication rolling produced less twin boundaries, and the grain boundary quality is relatively high, and the three kinds The rolling results at different rolling speeds were analyzed, and the optimum rolling speed was obtained at 5 m.min-1. The corresponding optimized rolling process is proposed to provide reference for the texture control and performance optimization of the rolled base strip. After the final cold rolling and annealing, the length of 20 m, the thickness of ~ 63 μm and the cubic texture content of ~ 99% <10 °), uniform performance of Ni5W alloy base band, laid the foundation for industrial production of Ni5W alloy base band.
