The effect of varying the solution treatment temperature, natural aging treatment and artificial aging treatment on the mechanical strength of 7249 aluminum alloy
Aluminum 7249 alloy was processed into 135 different conditions. The variables studied were five solution treatment temperatures (445degreesC-505degreesC), three quenching media (water, 20% polyalkylene glycol, and air), three natural aging times (0, 4, and 168 hours) and three artificial aging temperatures (111degreesC, 121degreesC, and 131degreesC). The effect of these variables on the tensile behavior, hardness measurements and electrical resistivity measurements were studied.
