摘要：
The microstructure, hardness and corrosion resistance of AZ91D alloy were investigated under different solution treatments and artificial aging conditions. When as-cast AZ91D alloy was heat treated at 415 degrees C by solution treatment for 12 h and artificially aged at 200 degrees C, the volume fraction of precipitates increased with the aging time up to 10 h. When as-cast AZ91D alloy was treated at 430 degrees C by solution treatment for 12 h and artificially aged at 200 degrees C for 10 h, the volume fraction of precipitates reached a peak value. The results of the corrosion test showed that a high corrosion resisting of the second phase precipitates was beneficial to improving the strength and hardness. Solution treatment at 445 degrees C temperature for 12 h destroied the consecutiveness of beta-Mg17Al12 phases.
