| Abstract | The microstructural evolution and mechanical properties of the 6082 alloys with different Mn content were systematically investigated to deeply understand the influence of Mn on the negative natural aging (NA) effect. It is found that alpha-Al(Mn,Fe)Si precipitated during homogenization is larger in size and less in amount in the alloy with lower Mn content, resulting in the less consumption of Si to create a relatively Si-rich environment in the matrix. The true Mg/Si ratio of alloy with higher Mn content is higher so that the alloy possesses a stronger negative natural aging effect. Additionally, four types of aggregates including clusters, GP zones, elongated ss '' and ss' are present in the microstructures aged at 175 degrees C/8 h which is the peak artificial aging (AA) treatment in the two alloys. The number density of ss '' and the total number density of the aggregates in alloy with lower Mn content is always higher than that in alloy with higher Mn content at the same heat treatment condition, which lead to the higher hardness and strength. |
