摘　　要：对不同前梁出口温度的6101铝合金挤压材进行不同温度的时效处理,通过OM、SEM、EDS、拉伸测试、导电率检测等测试方法对相应热处理后的6101铝合金样品进行了性能检测。结果表明,当前梁出口温度为450℃时,采用280℃×48 h时效工艺的6101合金的综合性能较优,其抗拉强度为132 MPa,导电率为59.8%IACS;当前梁出口温度为500℃时,采用270℃×48 h时效工艺的6101合金的综合性能较优,其抗拉强度为141 MPa,导电率为59.7%IACS。在这两种工艺条件下,6101铝合金挤压材都能满足产品强度及导电性能要求。6101 aluminum alloy extrusions with different front beam outlet temperatures were aged by different aging processes,and the 6101 aluminum alloy specimens after corresponding heat treatment were tested by OM,SEM,EDS,tensile test,conductivity test and other test methods.The results show that the comprehensive properties of the 6101 alloy are preferable when the front beam outlet temperature is 450 C and the process is aging at 280 C for 48 h,the tensile strength is 132 MPa and the conductivity is 59.8%IACS.When the front beam outlet temperature is 500℃and the process is aging at 270℃ for 48 h,the 6101 alloy can obtain preferable comprehensive properties,its tensile strength is 141 MPa and conductivity is 59.7%IACS.Under the both process conditions,6101 aluminum alloy extrusion can meet the product requirements of high strength and high conductivity characteristics.
