Cast Microstructure

Effects of different species of Sr additives (pure Sr, cast Mg-10Sr block, Ф10mm extruded Al-10Sr bar) on as-cast microstructure and tensile properties both at ambient temperature and elevated temperature of AS31 alloy were studied. The experimental results showed that pure Sr, Mg-10Sr, Al-10Sr additions all could refine the grains of AS31 alloy obviously, modify the eutectic Mg2Si particles and strengthen AS31 alloy. Al-10Sr is most effective to refine microstructure and improve mechanical properties of AS31 alloy.

Short Time

The mechanical properties of 2219-T87 and 2219-T6 aluminum were determined after soak times from 0 to 300 sec at temperatures from 300 deg F (149 deg C) to 600 deg F (316 deg C). Specimens were tested also at ambient temperatures after a soaking period of 300 sec at temperatures of 200 deg F (93 deg C) to 700 deg F (371 deg C). In general, the tensile strength of the 2219 aluminum alloy decreased with increasing temperature. The tensile properties were not significantly influenced by variations in the soak times used through 500 deg F (260 deg C). At 600 deg F (316 deg C), increasing the soak time affected the strength slightly. For relatively short time exposures, this material can be recommended for load-bearing applications to 400 deg F (204 deg C), at which temperature 70 percent of the ambient temperature strength is still retained. When tested at ambient temperature after exposure to 400 deg F (204 deg C) for 300 sec, 2219-T87 retained approximately 97 percent of its original ambient temperature strength.
