Paper Title:
Effects of the Copper Addition on the Precipitation of Al-Mg-Si Alloys
  Abstract

The effect of the copper additions on the heating process and the microstructure of 6082Al-Mg-Si alloys was investigated. The results show that there are four exothermic peaks from 50°C to 450°C in the Al-Mg-Si-0.6%Cu alloys, and the center temperature of every peak is lower than the temperature in the Al-Mg-Si alloys. Based on the observation of transmission electron microscope and three-dimensional atom probe, it is found that the copper reduce the precipitated time and the precipitated temperature of the precipitates. The number of the precipitates in the Al-Mg-Si-0.6%Cu alloys increased.
