a Engineering stress−engineering strain curves of α−β Ti-0.45O-4Fe alloy prepared by PBF-LB with different process parameters and subsequently annealed at 800 °C for 1 h. The good reproducibility of these curves causes some overlap. To improve distinguishability, we have set the stress-axis to start at 500 MPa. The symbol d denotes laser spot size. b Comparison of tensile yield strength (σ0.2) versus uniform elongation (εUEL) for α−β Ti-0.45O-4Fe alloy and other α−β titanium alloys. Orange, blue and red solid stars: Ti-0.45O-4Fe alloy (this work). Orange: after PBF-LB. Blue: after PBF-LB + annealing (εUEL < 14%). Red: after PBF-LB + annealing (εUEL ≥ 14%).
