Figure 15. Lattice strain and intensity evolution in Ti-38Al-10Nb alloys subjected to double loading with an intermediate holding stage at 800 °C. (A) Lattice strain vs. true stress/holding time curves for α₂ and γ reflections during the first loading; (B) Intensity vs. true stress curves for the (20$$ \bar{2} $$0)_α2 and (040)_O reflections during the first loading; (C) Lattice strain vs. holding time curves for the α₂ reflections during the intermediate holding; (D) Intensity vs. holding time curves for the (20$$ \bar{2} $$0)_α2 and (040)_O reflections during the intermediate holding; (E) Lattice strain vs. true stress curves for the α₂ and γ reflections during the second loading; (F) Intensity vs. true stress curves for the (20$$ \bar{2} $$0)_α2 and (040)_O reflections during the second loading. The lattice strains of the γ reflections during the intermediate holding are omitted for clarity. (Reproduced from Ref.[37]^[37]).
