摘　　要：为满足电子器件制造的需要,研制了1种电阻率≥1.5μΩ·m,厚0.01mm,厚度公差±0.001mm的NiMoCrAlSiTi镍基高电阻箔材。合金成分设计采用多元少量原则,在提高电阻率的同时保持良好的加工塑性;在中间热处理、箔材轧制等环节采取有效措施保证了尺寸公差;用扫描电镜(SEM)和透射电镜(TEM)对不同处理状态合金的显微组织、拉伸断口和析出相进行了观察分析,测试了不同状态合金的力学和电学性能,根据其结果决定采用冷轧+时效的最终热处理工艺,此工艺条件下合金析出弥散分布的二相粒子,对提高合金的电阻率有显著贡献,同时合金亦具有良好的加工性能。In order to meet the demands of engineering project,the nickel base high resistance foil material with resistivity not less than 1.5 μΩ·m,thickness size of 0.01 mm has produced.The alloying component design is on the principle of low alloying with multiple elements,which can enhance both resistivity and plasticity.During the intermediate annealing,foil material rolling,the effective action has been taken to guarantee the size tolerance;Combining cold rolling with aging treatment as the final heat treatment,one greatly increase the resistivity of materials.Using optical microcopy,SEM,TEM,and mechanical test,the relationship between the processing,the microstructure and the performance of materials has been analyzed.
