Abstract
Aluminium of commercial purity is deformed under hot working condition s at a strain rate of 1.16 s(-1) and at temperatures of 300, 350, 400, 450, and 500 degrees C up to a strain of epsilon = 0.9. TEM observati on reveals a well developed subgrain structure. The sizes of the subgr ains obey a log-normal distribution with an increasing fraction of ver y large subgrains as the temperature rises. A strong interrelation bet ween stress, temperature, and distribution-related parameters is found .
