Figure 5. Compression behavior of Ti-45Al-8Nb-0.2W-0.2B-0.02Y alloys with (A and B) nearly lamellar and (C) duplex microstructures at 800 °C. (A) True stress-lattice strain curves for α₂ and γ reflections; a detailed view of the α₂ lattice strain evolution in stage III is provided below. (Reproduced from Ref.[65]^[65]); (B and C) Von-Mises stress of α₂ and γ phases plotted against true stress for (B) the nearly lamellar (Reproduced from Ref.[65]^[65]) and (C) the duplex microstructure (Reproduced from Ref.[66]^[66]).
