Figure 10. Stress-strain curves (A) at room temperature and (B) at 650 °C for the T840-30, T880-30, and T920-30 specimens; (C) comparison of room-temperature ultimate tensile strength and uniform elongation and (D) comparison of specific ultimate tensile strength and elongation at 650 °C with previously reported Ti₂AlNb-based alloys produced by forging, hot rolling, AM and PM. AM: Additive manufacturing; PM: powder metallurgy.
