摘　　要：通过显微组织观察、力学性能测试、杯突试验等手段研究了退火工艺参数对劳保鞋内包头用6061铝合金板材显微组织、力学性能和成形性能的影响。结果表明:随着退火温度的升高和保温时间的延长,合金由纤维状组织向再结晶组织转变,合金强度降低,伸长率和杯突值增大;而随着退火温度进一步升高,合金固溶强化效果加强,合金强度增大,伸长率和杯突值降低。6061铝合金的最佳退火工艺为380℃保温1 h,在此条件下,合金的显微组织、力学性能及成形性能的配合较好。The effects of annealing process parameters on microstructure,mechanical properties and forming properties of 6061 alumi⁃num alloy plates were investigated by microstructure observation,tensile testing and Erichsen test.The results show that microstructure of the alloy develops from a fibrous structure into a recrystallized structure with increasing the annealing temperature and annealing time,resulting in the decreases of strength and the increase of elongation and erichsen value.With the further increase of the annealing temperature,the solution strengthening effect is enhanced,resulting in the increases of strength and the decrease of elongation and Er⁃ichsen value.The optimum annealing process for 6061 aluminum alloy is at 380℃for 1 h,the microstructure,mechanical properties and forming properties of 6061 aluminum alloy make a good combination under this condition.
