【摘要】：鋁電工圓桿是電纜、電線的坯料,其質量好壞直接影響鋁導線的優(yōu)劣。通過掃描電鏡、X射線物相分析等方法,對比鑄態(tài)、軋制態(tài)和形變時效態(tài)下不同Cu含量的稀土鋁電工圓桿的抗拉強度和導電率,研究形變熱處理對鋁電工圓桿的影響。結果表明:經(jīng)過形變熱處理后,試樣的晶界得到薄化,組織更加均勻;當Cu含量為0.2%時,通過(500℃,3 h固溶處理)+85%軋制+(150℃,12 h時效)的形變熱處理,試樣抗拉強度達到179 MPa,導電率為60.78%IACS,綜合性能較佳。
[Abstract]:The aluminum electrician round rod is the billet of cable and wire, and its quality directly affects the quality of aluminum wire. By means of scanning electron microscope (SEM) and X-ray phase analysis, the as-cast state is compared. The tensile strength and conductivity of rare earth aluminum electrotechnical circular bar with different Cu content in rolling and deformed aging state are studied. The effect of thermomechanical treatment on aluminum electrical circular rod is studied. The results show that the grain boundary of the sample is thinned after the deformation heat treatment. The microstructure is more uniform, and when Cu content is 0.2, the tensile strength of the sample is 179MPa, the conductivity is 60.78IACSs, and the comprehensive properties are better when the Cu content is 0.2and treated by solution treatment at 500 鈩，
