The effects of different solid solution and aging technologies on the microstructure of AM50 were studied. The results indicated that heat-resistant Al-Mn phases were the major second phases in AM50 alloy under all testing conditions. Highest microhardnesses were obtained not only in as-aged sample but in as-solution treated sample, which indicated that the strengthening mechanism for AM50 alloy was not limited to precipitation reinforcement.
