摘要： 为了探讨显微组织与形变织构的相关性,对纯铜线材运用精确的线材织构测定方法进行织构测定,采用取向分布函数法(ODF)分析了织构沿纯铜线材径向的分布.研究表明:单晶铜线材表面织构组分由〈100〉,〈112〉与〈110〉组成.由表及里〈100〉呈现增加趋势,并在中心层成为主要织构组分;〈112〉先增加后减少;〈110〉呈现减少趋势.多晶铜线材表面织构组分有〈100〉,〈111〉,〈112〉.由表及里〈100〉呈现先增加后减少;〈111〉呈现增加趋势,并在中心层与〈100〉成为主要织构组分;〈112〉先减少后增加.

Abstract: To explore the correlation between microstructure and deformation texture, the textures of copper wire were investigated in detail by XRD with a precision texture measurement suitable for wire samples provided. The radial distribution of deformation textures was analyzed by means of ODF. The results demonstrated that the surface textures of single-crystal copper wire consist of <100>, <112> and <110>, among which the <100> increases from surface to center of the wire and becomes the main texture in central layer, while <112> tends to increase then decrease from surface to center and <110> tends to decrease. However, the surface textures of poly-crystal copper wire consist of <100>, <112> and <111>, among which <100> tends to increase then decrease and <112> tends to decrease then increase from surface to center, while <111> tends to increase and both <100> and <111> become the main texture in central layer.
