摘要:
采用粉末套管法和集束拉拔技术，成功制备出石墨烯包覆铌粉增强Cu-Nb（73芯）的复合线材（Cu-Nb-C）和纯铌粉增强Cu-Nb（73芯）的复合线材(Cu-Nb)。对两种复合线材的芯丝组态、微观组织进行表征，结果表明，引入石墨烯掺杂的Cu-Nb-C线材的芯丝形态较规则、分布较均匀，这是由于石墨烯优异的润滑特性很好地协调了Cu基体和Nb芯丝之间的塑性变形。对不同尺寸的Cu-Nb-C线材和Cu-Nb线材力学性能和导电性能进行测试，结果表明，相比于Cu-Nb线材，Cu-Nb-C线材的力学强度虽然仅提高了几十兆帕,但其导电性明显增强，提高了近9%。石墨烯本身优异的特性及线材芯丝的均匀分布是其导电性提高的主要原因，本实验研究可为发展新一代高强高导Cu-Nb复合线材提供一些理论依据和实验基础。
Abstract:
Cu-Nb was reinforced by graphene coated niobium powder and pure niobium powder to prepare Cu-Nb-C microcomposite 73 filaments and Cu-Nb microcomposite 73 filaments by powder casing method and bundle-drawing technology. Through the characterization of filaments configuration and the microstructure of two kinds of wires, it is found the filaments distribution with introduction of graphene doping is relatively regular and uniform, due to the lubricating property of graphene well coordinating the deformation between Cu matrix and Nb filaments. Through the analysis of mechanical properties and electrical conductivity of two wires with different sizes, the results show that the strength of Cu-Nb-C wires increases with only tens of MPa compared with Cu-Nb wires, however, the conductivity of the Cu-Nb-C wire increases obviously, which reaches 9%. The excellent properties of graphene itself and the uniform distribution of filaments are the main reasons for the improvement of conductivity, which may provide theoretical basis and experimental basis for the development of a new generation of highstrength and high-conductivity Cu-Nb composite wires.
