X-Ray Topographic Studies of Deformation in Niobium and Dilute Niobium-Hydrogen Alloys
An experimental study of the deformation at a notch under tensile loading and by hydride precipitation has been conducted with x-ray diffraction topography. Lang topography, asymmetric crystal topography (ACT) and synchrotron white beam topography (WBT) were applied in this study. Crystals suitable for transmission x-ray topography (i.e. dislocation densities below 10('6) cm('-2)) were grown by the strain-anneal technique from ribbons of polycrystalline niobium of thickness less than 0.2 mm.
