摘要
对530℃固溶处理后的6060铝合金进行了不同变形量下的室温轧制,研究了随后的时效处理温度和轧制变形量对合金微观组织结构、力学性能及导电率的影响。结果表明,合金的强度随轧制变形量的增大而升高,而伸长率有所下降;经70%变形量轧制后于180℃时效处理的合金的综合力学性能和导电率匹配较佳。合金的时效析出过程和微结构演化决定了6060铝合金的导电率和强度。
Effects of rolling deformation and aging temperature on microstructure,mechanical properties and electrical conductivity of the6060 aluminum alloy after solution treatment at 530 ℃ were investigated. The results show that the yield strength and the ultimate strength of the rolled 6060 aluminum alloy increase with the increasing of deformation reduction,while the elongation of the alloy decreases accordingly. A better synergy between the strength and the electrical conductivity of the alloy is achieved through the 70% rolling reduction and aging at 180 ℃. The electrical conductivity and strength of the alloy are determined by the microstructure evolution during aging treatment.
