摘要：
Second-phase Al3Sc particles play an important role in several aspects of material performance. These include increasing strength, stabilizing microstructure and increasing recrystallization temperature and thermal stability. The present work was conducted to investigate the stability of Al3Sc particles in a severely deformed Al-0.25 wt% Sc alloy at room temperature in comparison to that of Al2Cu precipitates in an Al-Cu alloy. Microstructural examination and hardness tests showed that the Al3Sc particles were coarsening resistant with substantially higher stability than Al2Cu and the hardness of the Al-0.25Sc alloy remained almost constant while an apparent hardness drop was observed for the Al-Cu alloy.
