英文摘要	Single crystal copper was connected using cold pressure welding and the influence of compression on the joint microstructure and properties were studied in order to achieve effective connection and not lose the conductivity of single crystal high purity copper as possible. The results showed that an effective joint could not be formed during the cold pressure welding joint connection of single crystal copper when the compression was small. Only when the amount of compression reached a critical value, an effective joint could be formed. In the axial direction of joint, the base material region and the deformation region still maintained a single crystal structure, but their grain orientations changed. With the increase of deformation, the single crystal structure at the joint interface was destroyed and the fine recrystallized grains at the joint increased and then decreased. It consisted of a large number of fine grains with different orientations and a deformation band structure. The grain size at the interface was gradually reduced, and the tensile strength of joint was increased and then slightly decreased. The cold pressure welding joints kept good electrical conductivity. © 2020, Materials Review Magazine. All right reserved.
