The Study on Precipitation Characteristics in 6082 Aluminum Alloy with Cu Addition

Abstract:

The effects of Cu addition on precipitation characteristics in 6082 Al-Mg-Si alloy was investigated by means of DSC、TEM and 3DAP. It was found that addition of Cu has distinct effect on the precipitation and dissolution process of precipitates during heating by DSC measurement, the presence of Cu promotes the formation of GP zone or atomic clusters and accelerates the precipitation of β¢¢ . The precipitation sequence in the 6082 alloy with 0.6%Cu addition is as follows: SSSS atomic clusters/GP-zonesβ¢¢ + Q¢ Q¢.
