【摘要】 在Gleeble 15 0 0热模拟机上对 6 2 0 1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 5 40℃ ,可加速固溶 ;变形终了温度为 30 0℃ ,加速了Mg2 Si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 6 2 0 1铝合金热连轧的变形抗力模型。更多还原

【Abstract】 Continuous hot rolling of 6201 aluminum alloy was simulated on Gleeble 1500. 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 hot rolling, 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.更多还原
