摘要
采用集束拉拔技术制备出应用于高脉冲磁场绕组材料的高强度和高导电性Cu-18vol%Nb复合线材(873~3芯)。通过XRD、SEM和TEM对线材样品微观组织,力学性能及磁化曲线进行表征。结果表明,随着退火温度的升高,Nb(110)衍射峰的强度先减弱后增强锐,同时观察到了Nb芯丝显著的球化和粗化现象。最后探讨了材料微观结构变化对Cu-Nb复合材料力学性能和磁性能影响的微观机理。
The high strength and high conductivity Cu-18 vol%Nb composites(8733 filaments)used in high pulsed magnets field were fabricated by bundling and drawing process(ADB).The influence of heat treatment on the microstructure,mechanical properties and magnetic properties of Cu-18 vol%Nb composites was investigated.The samples were characterized by XRD,SEM,and TEM.Results show that the intensity of<110>Nb texture decreases first and then increases with the increases of annealing temperature.At the same time,significant spheroidization and coarsening phenomenon of the Nb filaments are observed.The influence of the microstructural change on the mechanical properties and the magnetic properties of the Cu-Nb composites was also discussed.
