Cu-Nb复合材料除了在Nb_3Sn超导材料中显示一定的优点之外,它还是一种很有前途的高强度、导电、非磁性材料,有其他用途。采用真空自耗电弧炉可以熔炼出高质量铸锭,优于真空感应熔炼法。研究了Nb含量与强度、导电性能的关系,冷加工率与强度、导电性能的关系。还探讨了添加稀土金属Ce对性能的影响,Nb在铜基体的状态。 Cu-Nb composites, besides showing certain advantages in Nb 3 Sn superconducting materials, are promising other high-strength, conductive and nonmagnetic materials for other applications. Using vacuum consumable electric arc furnace can melt out high quality ingot, superior to vacuum induction melting method. The relationship between Nb content and strength and electrical conductivity, cold working rate, strength and electrical conductivity were studied. The effect of adding rare earth Ce on the properties was also discussed, with the state of Nb on the copper matrix.
