摘要
Modified 6005A alloy was reported and its mechanical properties were studied by tensile test, hardness measurement and TEM analysis. Results show that the favorable aging condition for 6005A is 175°Cfor 8h, and the nose temperature of its TTP (Time-temperature-properties) curves is about 370°C. In a moderate temperature zone (270°C <T <390°C), the alloy has much high quench sensitivity. Therefore, in on-line extrusion, water spray quench and moderate temperature should be taken to enhance quench rate, then 6005A alloy can be quench hardened and its quenching distortion can be
