摘　　要：为了得到力学性能优异的铝合金建筑型材,对6系铸造态铝合金进行高温固溶和退火处理,并在不同温度下进行轧制变形。对最终产品进行显微硬度测试,结果发现,固溶处理+180℃轧制得到的6系铝合金建筑型材的硬度达到最大,为158Hv。对不同条件下得到的产品进行相组成观察,并对他们的强化机制进行分析。To obtain the A1 alloys with suitable mechanical properties, 6XXX A1 alloys was solid-solution treated and then cooled down in two ways： water-quenched and furnace-cooled. The alloy samples in the two cooling conditions were roiled at different temperatures. The hardness of the rolled alloys reached their peak values （158 Hv） at the processes of water-quenched and 180 ℃ rolling. X-ray diffraction analyses were performed to confirm the phases of the alloys, and the main strengthening mechanisms of the alloys under different rolling temperatures were discussed.
