摘　　要：采用室温拉伸试验研究不同固溶时间对25mm厚6016铝合金板材力学性能的影响,结合金相显微镜(OM)与扫描电镜(SEM)分析和探讨其影响机理。结果表明,随着固溶制度的变化,板材内部再结晶晶粒逐渐长大,同时板材内部黑色Mg-Si相逐渐溶于基体,富铁相尺寸逐渐变小,圆整化。In this paper,the effects of different solution time on the mechanical properties of 25mm thick 6016 aluminum alloy sheets is studied by tensile test at room temperature,and the mechanism of the influence is discussed by metallography microscopy(OM)and scanning electron microscopy(OM)and scanning electron microscopy(SEM).The results show that with the change of the solution system,the recrystallized grains in the plate gradually grow,and the black Mg-Si phase in the plate gradually dissolves in the matrix.The size of the iron-rich phase gradually decreases and becomes round.
