摘要:
通过第一性原理计算、硬度测试、拉伸测试、X射线衍射（XRD）以及透射电镜（TEM）等手段研究了预时效处理对6016合金机械性能以及析出行为的影响. 研究表明: 预时效处理能够抑制自然时效的负作用, 其中110℃×10min预时效处理能够显著抑制板材的自然时效, 使板材保持良好的成形性(σ0.2: 109.65MPa); 预时效能够提高烤漆强化效应, 110℃×10min预时效处理的烤漆性能最优(σ0.2:212.29MPa), 且随着预时效时间的增加和温度的升高, 烤漆强化效应降低; 不同预时效处理并不能改变基体中相的成分, 主要为α-Al和Mg2Si两种相，且随时间的增加和温度的升高, Mg2Si相略微增多; 预时效处理后的试样在烤漆之后有更多针状的β"相析出且机械性能更好, 这与第一性原理计算的β序列的理化性质相符合.
