| 摘 要： | 本文利用电子背散射衍射(EBSD)技术,对含不同铌芯丝数的Cu/Nb微观复合线材中的Cu沿径向的织构进行了表征.结果表明:复合线材在拉拔过程中,各层织构存在差异,织构种类由表及里减少,且主要向平行于拉拔方向的〈111〉丝织构聚集；对于复合不同道次的样品,在相同部位,变形量大的线材内部织构更集中于〈111〉织构组分.

| Abstract: | This study focused on the radial textures of Cu in Cu/Nb composite wires characterized by electron backscatter diffraction（EBSD） technique.The results showed that during the drawing process,there were differences in the textures from the surface to the center.The types of textures decreased from the surface to the center,and they mainly transformed to a major 〈111〉 fiber texture which was parallel to the drawing direction.In the equivalent areas in the wires with different strain,the more deformation the wire suffered,the fewer the types of the textures were and the stronger the 〈111〉 fiber texture was. |
