摘  要:采用轧制辅助双轴织构技术(RABi TS)制备了无磁性强立方织构的Cu60Ni40合金基带。对Cu60Ni40合金基带冷轧及再结晶退火后的织构进行分析。结果表明:轧制总变形量及再结晶退火工艺是影响Cu60Ni40合金基带再结晶晶粒取向的主要因素。经过大变形量冷轧,Cu60Ni40合金基带表面可以得到典型的铜型轧制织构。通过优化的冷轧及两步再结晶退火工艺获得了立方织构含量高达99.7%(≤10°)、小角度晶界含量高达95.1%的Cu60Ni40合金基带,Σ3孪晶界含量为0.1%。The non-magnetic Cu60Ni40 alloy substrates containing strong cube texture were prepared by rolling assisted biaxially textured technology(RABi TS). The surface textures of the Cu60Ni40 alloy substrates after cold-rolling and the recrystallization treatment were studied. The results show that the key factors that influence grain orientation in Cu60Ni40 alloy substrate are the total amount of rolling deformation and recrystallization annealing process. Through the large deformation of cold-rolling, the strong copper-type rolling texture in the Cu60Ni40 alloy substrates can be obtained. The content of the cube texture(≤10°), the fraction of small angle and Σ3 grain boundaries in the Cu60Ni40 alloy substrates prepared by optimized cold rolling and two-step recrystallization annealing process are 99.7%, 95.1% and 0.1%, respectively.
