摘　　要： 采用放电等离子烧结技术(SPS)制备出表层为Ni-5%W(摩尔分数)合金、芯层为Ni-12%W(摩尔分数)合金的复合坯锭,经热轧和冷轧后获得长度为10m的复合基带。结果表明:冷轧基带界面连接性良好,能够满足大变形量冷轧工艺的要求。对复合基带的厚度及织构均匀性分析表明,在全长度范围内基带的厚度为(75±3)μm,其外层立方织构含量均在97%(<10°)以上,与商业化Ni5W基带水平相当。同时,对其力学性能与磁性能进行分析,结果表明复合长带的屈服强度为240MPa,饱和磁化强度仅为Ni5W基带的40%。采用复合坯锭路线在规模化生产高性能复合基带方面具有一定的应用潜力。 A tri-layer composite ingot with Ni-5%W （mole fraction） alloy as the outer layer coupled with Ni-12%W （mole fraction） alloy as the inner layer was fabricated by sparking plasma sintering method. A 10 m length composite tape was prepared by traditional hot rolling and cold rolling process. The results show that the connectivity between the outer layer and inner layer of the composite tape is good enough during the heavy cold rolling process. The evaluation of the uniformity for both the thickness and texture in the whole tape shows that the thickness of the obtained composite tape is （75±3） μm and the cube texture is about 97%（10°）,which is the same as the level of the commercial Ni5W tape. The analyses of mechanical and magnetic properties indicate that the yield stress of the composite substrate is 240 MPa and the saturation magnetization is only 40% of that of the commercial Ni5W tape. Consequently,the preparation route of composite ingot solution has a potential application to manufacture the long-scale composite substrate used for coated conductors.
