Figure 9.9. (a) Bright-fi eld two-beam image recorded using g = (011) β showing diffraction
contrast from the dislocations within the shear bands in the tensile deformed TNZT sample.
A set of bright-fi eld images recorded from the exact same region using different two-beam
imaging conditions are shown in (b) and (c). (b) has been recorded using g = (011) β while (c)
has been recorded using g = (-1-21) β . While the dislocation contrast is clearly visible in (b), it is
invisible in (c). [Rajarshi Banerjee et al. Laser Deposited Ti - Nb - Zr - Ta Orthopedic Alloys (J. Bio.
