为了获得既有良好力学性能又有较高导电性能的铝导线，采用连续流变挤压技术制备出直径为9.5 mm的Al-0.16Zr、Al-0.16Sc、Al-0.12Sc-0.04Zr(质量分数，%)和高纯铝(99.996%)4种铝导线，随后对3种铝合金导线进行热处理，并进行分析测试。结果表明：向高纯铝中单独添加0.16% Sc和0.16% Zr可以提高铝导线的抗拉强度，降低铝导线的导电性能。在高纯铝中添加0.12%Sc 和0.04%Zr 的合金也具有相同的规律。经过热处理， Al-0.12Sc-0.04Zr铝合金导线可以达到抗拉强度和导电率的最优综合性能：抗拉强度为160 MPa，导电率为64.03%(IACS)。

In order to obtain the Al wires with good mechanical properties and high electrical conductivities, conductive wires of Al-0.16Zr, Al-0.16Sc, Al-0.12Sc-0.04Zr (mass fraction, %) and pure Al (99.996%) were produced with the diameter of 9.5 mm by continuous rheo-extrusion technology, and the extruded materials were heat treated and analyzed. The results show that the separate additions of 0.16% Sc and 0.16% Zr to pure Al improve the ultimate tensile strength but reduce the electrical conductivity, and the similar trend is found in the Al-0.12Sc-0.04Zr alloy. After the subsequent heat treatment, the wire with the optimum comprehensive properties is Al-0.12Sc-0.04Zr alloy, of which the ultimate tensile strength and electrical conductivity reach 160 MPa and 64.03% (IACS), respectively.
