Figure 5From: Formation of self-organized Zircaloy-4 oxide nanotubes in organic viscous electrolyte via anodizationXRD patterns. As-received Zr-4 sheet (a). As-anodized (b) and annealed (c) Zr-4 oxide nanotubes. XRD patterns of the Zr-4 oxide nanotubes clearly show that the as-anodized nanotubes were crystalline in cubic phase which is transformed into monoclinic after annealing.Back to article page
