摘要： The present invention relates to the reduction of artificial aging time of 7xxx series alloys. Currently, the artificial aging times for typical 7xxx series alloy can be as long as 24 hrs. The current invention allows for a significant reduction of aging times, thereby saving time, energy, money and storage space hence increasing the productivity.
