Conclusions

  1. 1.

    During decomposition of the supersaturated solid solution in binary Al−Mg alloys the microstructure changes in three stages: 1) appearance of boundaries of dendritic cells; 2) decomposition in grain boundaries and in β phase sites; 3) decomposition between β phase sites.

     
  2. 2.

    Increasing the magnesium concentration lowers the temperature at which the cellular structure appears.
