✦ Synopsis
The variables studied in the heat treatment processes of the 7249 aluminum alloy were 5 solution treatment temperatures (445-505 C), 3 quenching media (water, 20% polyalkylene glycol, and air), 3 natural aging times (0, 4, and 168 h) and 3 artificial aging temperatures (111, 121, and 131 C). The effect of varying these parameters on the mechanical strength was discussed. Quenching is identified to be the most critical step in this process.
