Figure 4. (A) True stress vs. lattice strain curves for the α₂, γ, and β_o reflections. Equiaxed grained TNM-TiAl alloys were stretched at room temperature. (Reproduced from Ref.[61]^[61]); (B) Development of the lattice strains revealed by sample gage length scanning interrupted at 1000 cycles in the fatigue deformation of high Nb-TiAl alloy at 850 °C. (Reproduced from Ref.[62]^[62]); (C) Residual stresses of the α₂ and γ phases varying with increasing volume fraction of the lamellar structures. (Reproduced from Ref.[11]^[11]).
