摘要
采用连铸连轧和拉拔工艺制备Al-0.8Mg-0.7Si合金导线,利用直流双臂电桥和拉伸试验机,研究了自然时效和人工时效工艺对Al-0.8Mg-0.7Si合金导线抗拉强度和电导率的影响.结果表明:随着自然时效时间延长,铝合金导线的抗拉强度提高,导电率下降.当自然时效192h时,铝合金导线的抗拉强度达到最大值318MPa,导电率为52.5%IACS.随着人工时效时间延长,铝合金导线的抗拉强度和导电率提高.在175℃人工时效8h时,铝合金导线的抗拉强度达到最大值330 MPa,导电率为55.6%IACS.
The Al-0. 8Mg-0. 7Si alloy wires were prepared by continuous casting-rolling and drawing process. The effects of natural aging and artificial aging process on tensile strength and conductivity of Al- 0. 8Mg-0. 7Si alloy wires were investigated by electrical conductivity measurement and tensile testing machine. The results show that with the extension of natural aging time, the tensile strength of alloy wire is increased gradually, while the Conductivity is decreased gradually. The maximum tensile strength of alloy wire with natural aging is 318MPa, while the conductivity is 52.5%IACS. With the prolongation of artificial aging time, the tensile strength and conductivity of alloy wires are increased gradually. At the artificial aging process of 175 ℃ with 8h, the maximum tensile strength of alloy wire is 330MPa and the conductivity is 55.6%0IACS.
