REDUCED AGING TIME OF 7XXX SERIES ALLOY |
| 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. |

1. A method for achieving desired yield strength and elongation in an 7xxx aluminum alloy sheet comprising:
a) rapidly heating the sheet to a temperature of 450° C. to 510° C.; b) maintaining the sheet at the temperature of 450° C. to 510° C. for up to 20 minutes; c) rapidly cooling the sheet to room temperature at more than 50° C. per second; d) heating the sheet to a temperature between about 50° C. and 150° C.; e) maintaining the sheet at the temperature between about 50° C. and 150° C. for a duration of about 0.5 hrs to 6 hrs. |
