TEM image comparison for dislocation substructures in EBM-fabricated Ti-6Al-4V components as in Figure 9(a). (a) Low dislocation density and shallow 𝛽 wall thickness surrounding 𝛼-phase grains. (b) High dislocation density and thicker 𝛽 phase surrounding 𝛼-grains. Hardness in (a) and (b) was HV 3.6 and 3.9 GPa, respectively.
