    • The zirconium content of the alloy composition of a copper alloy wire is 3.0 to 7.0 atomic percent; and the copper alloy wire includes copper matrix phases and composite phases composed of copper-zirconium compound phases and copper phases. The copper matrix phases and the composite phases form a matrix phase-composite phase fibrous structure and are arranged alternately parallel to an axial direction as viewed in a cross-section parallel to the axial direction and including a central axis. The copper-zirconium compound phases and the copper phases in the composite phases also form a composite phase inner fibrous structure and are arranged alternately parallel to the axial direction at a phase pitch of 50 nm or less as viewed in the above cross-section. This double fibrous structure presumably makes the copper alloy wire densely fibrous to provide a strengthening mechanism similar to the rule of mixture for fiber-reinforced composite materials.
    • 铜合金线的合金组成的锆含量为3.0〜7.0原子% 铜合金线包括铜基体相和由铜 - 锆化合物相和铜相组成的复合相。 铜基质相和复合相形成基体相 - 复合相纤维结构,并且在与轴向平行的横截面中观察并且包括中心轴线在轴向方向上交替平行布置。 复合相中的铜 - 锆化合物相和铜相也形成复合相内纤维结构,并且如上述横截面所示,以50nm以下的相位间距与轴向交替平行排列。 这种双重纤维结构可能使铜合金丝线密集纤维化,以提供类似于纤维增强复合材料的混合规则的强化机理。
