摘　　要：采用热等静压(HIP)法制备芯层为Ni-12%W(Ni12W,摩尔分数)合金、外层为Ni-5%W(Ni5W,摩尔分数)合金的Ni5W/Ni12W/Ni5W 3层复合初始坯锭;采用压延辅助双轴织构技术(RABiTSTM)通过直接冷轧及再结晶退火获得Ni5W/Ni12W/Ni5W复合基带;采用X射线四环衍射技术(XRD)及背散射电子衍射技术(EBSD)对复合基带表面冷轧及再结晶织构进行分析。结果表明:冷轧复合基带表面形成较强的铜型形变织构,再结晶退火后复合基带表面形成锐利的立方织构,其立方织构含量达到99.1%(≤10°),与商业用Ni5W合金基带水平相当。A tri-layer composite alloy ingot was fabricated by hot isostatic presses（HIP） method,in which the outer layer is Ni-5%W（Ni5W,mole fraction） alloy and the inner layer is Ni-12%W（Ni12W,mole fraction） alloy.The composite ingot was cold-rolled using the process of rolling assisted biaxially textured substrate（RABiTSTM） technology and annealed to obtain the Ni5W/Ni12W/Ni5W composite substrate with high cube texture.The cold rolling and the recrystallization textures on the surface of the as-obtained composite substrate were studied systematically by X-ray and EBSD measurements.The results show that a strong deformation copper-type texture is obtained in the cold rolled composite substrate,and a sharp cube texture is formed on the surface of Ni5W/Ni12W/Ni5W composite substrate after a recrystallization annealing process.The percentage of the cube orientated grain within a misorientation angle of 10° is as high as 99.1%,which is in the same level as that of the commercial Ni5W tape.
