Nanocrystalline zirconium was studied by X-ray diffraction, transmission electron microscopy and differential scanning calorimetry to determine the microstructure, phase composition and thermal stability of this material. The presence of a phase transition during High Pressure Torsion at 4 GPa, and the reverse phase transition during annealing at 300 °C was revealed. It was shown during the study of mechanical properties that the main mechanism of plastic deformation is glide of prismatic dislocations, and at low temperatures a significant contribution to plastic deformation gives twinning.
