The kinetics of precipitation in supersaturated solid solution of 7050 aluminum alloy was investigated by a combination of differential scanning calorimetric (DSC) techniques with Johnson-Mehl-Avrami (JMA) equation. The results demonstrated that, the activation energy of GPI 353 K, η′ phase 492 K and η phase 510 K were 103.8, 195.1 and 571.9 kJ/mol, respectively. The constant of k0 were 1013 , 4.8×1016 and 7.9×1056 /s, respectively. The equations of the corresponding kinetics were gained at the same time..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
