Figure 7: Transmission electron microscope (TEM) observations of EBMfabricated, Z-axis solid cylinders. (a) α-β grain structure containing dislocation density of 1010 cm-2. (b) Magnified view of dislocations in α-grain. (c) Nearly dislocations free α grains. (d) Magnified view of α-βgrain structure in (c). Note Vickers microindentation hardness (HV) in (a) and (c).
