ABSTRACT AZ91D magnesium alloy was fabricated by using pre-alloyed powder compressed without any binder agent at 280oC under the compaction pressure of 200 MPa at different time intervals of 2, 4, 6, 8 and 10 hours. Some of the compressed samples were then undergone a sintering process at temperature of 450oC for 3 and 6 hours. Furnace cooling was performed after the sintering. Microstructure and hardness of each specimen were investigated. The microstructures observation and hardness investigation of the as-hot compacted and sintered samples were then compared. The results showed that microstructure transformation occurred due to the hot compaction and the sintering for 3 and 6 hours. The as-hot compacted samples showed a grown globular precipitates (β phase, Mg17Al12) distributed uniformly in grains. However, after sintering process, lamellar precipitates took place and dominated the grains. The as-hot compacted sample showed higher hardness value compared to the 3 hours and 6 hours sintered samples.
