摘　　要：研究了固溶温度、固溶时间以及固溶后空气中滞留时间对6082锻造铝合金控制臂显微组织和力学性能的影响。结果表明,固溶及时效处理后合金组织除固溶基体外,主要存在针状或球状的Mg2Si和棒状的Al Fe Mn Si两种析出相;随固溶温度升高和时间延长,时效后合金中析出相数量增加,合金硬度和强度上升,塑性下降;随着滞留时间延长,合金中析出相的数量减少,合金的硬度和强度下降,塑性升高。Effects of solution temperature and time,strand time in the air after solution treatment on microstructure and mechanical properties of 6082 forged aluminium alloy control arm were investigated. The results show that the alloy mainly consists of α（Al）,cicular and spherical Mg2 Si phase and rod Al Fe Mn Si phase after solution and aging treatment. The number of precipitate phase and hardness and strength of the alloy increase,and plastic decreases after aging treatment with the increasing solution temperature and time. The number of precipitate phase and hardness and strength of the alloy decrease,and plastic increases with the increasing strand time.
