This study focuses on the investigation of uniquely sequenced Cu-Al clad composite wires, which are considered as perspective materials for applications within a wide range of industrial and commercial branches. The wires were produced by rotary swaging under variable temperature (at 20 °C and 250 °C). The required diameter of the final wire was 5 mm, however, detailed analyses were performed on 10 mm, 7.5 mm, 6 mm and 5 mm samples. The swaged composite wires were studied from the viewpoints of deformation behaviour, structure and mutual interfaces, and electric and mechanical properties via scanning and transmission electron microscopy and neutron diffraction, testing of electrical resistivity, and mechanical testing with implemented acoustic emission detection. The results showed non-negligible effects of both the variables/influencing factors (swaging degree and temperature) on the investigated parameters. The development of intermetallics was observed at the interfaces of samples swaged with high swaging degrees, but only at 250 °C. These intermetallics provoked signal activity during acoustic emission detection and deteriorated the electric conductivity. On the other hand, substantial work hardening occurring during swaging at 20 °C also decreased the conductivity. By these reasons, the electric properties were the poorest for work hardened samples with occurring intermetallics. Both the final 5 mm composites exhibited satisfactory bonding of both the components and recrystallized structures with ultra-fine grains ensuring the ultimate tensile strength higher than 200 MPa.

这项研究的重点是研究独特顺序排列的Cu-Al复合金属丝，这些金属丝被认为是广泛应用于工业和商业分支的透视材料。通过在可变温度（在20°C和250°C）下旋转型锻生产线材。最终导线的所需直径为5 mm，但是，对10 mm，7.5 mm，6 mm和5 mm样品进行了详细分析。从变形行为，结构和相互界面以及通过扫描和透射电子显微镜和中子衍射，电阻率测试以及实施声发射检测的机械测试等方面的角度研究了型锻复合线。结果表明，变量/影响因素（弯曲度和温度）对所研究参数的影响均不可忽略。在高锻压度的样品界面上观察到金属间化合物的发展，但仅在250°C时。这些金属间化合物在声发射检测期间激发了信号活性，并降低了电导率。另一方面，在20°C锻造期间发生的大量加工硬化也降低了电导率。由于这些原因，对于出现金属间化合物的加工硬化样品，电性能最差。最终的5毫米复合材料都显示出令人满意的成分结合以及具有超细晶粒的重结晶结构，从而确保了超过200 MPa的极限拉伸强度。
