摘要 研究了将La加入Al-Mg-Si合金;将Y和Ce加入Al-21-Mg合金.获得Al-Mg-Si-La高强高导电缆合金和Al-Zr-Mg-Y-Ce耐热高导电缆合金.通过检测和组织观察,从而提高了电缆合金的强度.耐热性和导电性.另外稀土改善了铝合金的加工性能.减少了冷拉缺陷. We researched that managing La added into Al-Mg-Si alloy; and managing Y and Ce added into Al-Zr-Mg alloy. Obtaining Al-Mg-Si-La alloy with it to make cable, so that, it has high- strength and high- conductivity, also obtaining Al-Zr-Mg-Y-Ce alloy, with it to make cable, so that, it may heat resistant and has high conductivity. The two kinds of rare earth- aluminium alloy with it to make cable, and they had the electro-chemical performance; the mechanical performance and the workability, the all reached or exceeded to concerned standard whith were instituted by our nation. So then, in that case, cable alloy's strength, property of heat resistant and property of conduction were raising. Besides, the workability of aluminium alloy also improved by rare earth and decreased the faults at cold drawn.
