EXAMINATION OF AGING ALUMINUM 319

open in viewerThis project examined the effects of aging time and temperature on aluminum 319. The mechanical properties of cast tensile bars were recorded for various heat treatments, and then compared to published standards. The results indicate that aging at 190186C is an alternative to present T6 heat treating, as better strength was obtained in a shorter time. Aging at 190186C achieved peak strength in only 4 hours, whereas aging at 150186C (T6 standard) peak strength wasn't obtained until 24 hours of aging. Similarly, aging at 230186C showed an even faster peak, reaching peak strength in only 45 minutes, though the strength after this treatment wasn't as high as the strength after 4 hours at 190186C. Further experiments should be conducted between 170 and 240186C to optimize the aging process of aluminum 319.
