Directional orthorhombic phase precipitation and coarsening enable strength-ductility synergy in compositionally modified Ti<sub>2</sub>AlNb-based alloys

Figure 9. Statistical charts of the O-phase area fraction, interlamellar spacing, and lamellar thickness of the cold-rolled alloy after aging at 840, 880, and 920 °C for 30 min. The error bars represent the standard deviation (SD), with n = 5.
