Abstract

The precipitation sequence of Al-Mg-Ge alloy has been not clarified yet. The influence of the small amount of transition metals in Al-Mg-Si alloys had been reported by many researchers. It was known that some transition metals improved the mechanical property of Al-Mg-Si alloys. In this work, several transition metals (Cu and Ag) were selected and added to Al-1.0mass%Mg2Ge alloy. Hardness measurement and TEM observation were performed to investigate the age-hardening behavior of there alloy. We found that Al-Mg-Ge alloy including Ag showed a quick age-hardening rate at the initial aging stage, while Al-Mg-Ge alloy including Cu had the highest peak hardness.
