摘要：

The effect of the solution treatment and aging (STA) conditions on the tensile properties of Ti-4 mass% Fe-4 mass%Al-0.25 mass%Si alloy has been investigated in this work. The obtained results revealed that varying the solution temperature affected the stability of the beta phase due to the Fe partitioning (which inhibited the beta -> alpha'/alpha" reaction during water quenching), while the magnitude of the aging temperature determined the predominant products of the beta -> isothermal omega -> secondary alpha(rich)-> secondary alpha(lean) + TiFe phase transformation with distinct tensile characteristics. In addition, the relationship between the alloy microstructure and its tensile properties was discussed.
