XRD patterns taken from the TNA films under investigation at various stages of their fabrication process. Dotted lines mark respective XRD peaks from stress-free Ti-α crystal lattice (labeled with Miller indices). Similar positions of peaks of other crystalline phases are marked with their names, respectively (“subs.” stands for substrate).
