摘要
The present research aims to determine the precipitation and coarsening processes of Al3Sc phase in Al-6Mg-0.2Sc alloy. The electrical resistivity changes are recorded during the isothermal annealing, which reflects the different stages of the nucleation and growth processes of the Al3Sc precipitation. The experimental results show that the Sc addition can improve the mechanical property, and increase the recrystallization temperature of Al-Mg alloys.
