Figure 1

Characteristic structural features of the Ni-Mo-Nb alloy in the annealed condition (15 minutes at 1065°C). (a) Light optical micrograph showing the gross grain structure. (b) <100> selected-area electron diffraction pattern showing { 1 1 / 2 0 } short-range order reflections as indicated by the arrows. (c) Bright-field TEM image showing typical deformation substructure corresponding to 10% tensile elongation at room temperature.
