摘 要: 在Gleeble1500热模拟机上对6201铝合金的热连轧进行了实验模拟， 对变形时的变形力进行了测定，用TEM观察了变形后试样的微观组织并测量了其显微硬度。 结果发现： 由于应变诱发作用， 可以在热连轧过程中有效地实现快速固溶与时效处理的结合；变形开始温度为540℃， 可加速固溶； 变形终了温度为300 ℃，加速了Mg2Si粒子的充分析出； 变形抗力和硬度值在第6道次之前，随着道次增多而增加，之后有所回落。 此外， 实验还获得了6201铝合金热连轧的变形抗力模型。

Abstract:Continuous hotrolling of 6201 aluminum alloy was simulated on Gleeble1500. The deformed specimens were observed by TEM and the hardness was measured. It was shown that rapid solid solution and aging treatment can be effectively combined by the strain induced during continuous hotrolling, the deformation temperature ranges from 540℃ to 300 ℃, the hardness and the deformation resistance increase with increasing passes before 6 passes followed by a slight drop.
Key words: 6201 aluminum alloy; continuous hotrolling;thermal simulation
