Study of the Radiation Damage Kinetics in NbTiVZr High-Entropy Alloys Irradiated by Heavy Ions

The purpose of this paper was to study the kinetics accumulation radiation damage in near-surface layer a high-entropy NbTiVZr alloy upon irradiation with heavy Kr15+ ions and fluences 1010–1015 ion/cm2. According data X-ray diffraction analysis, it found that lead structural changes associated deformation distortions stresses. In case, nature tensile crystal lattice swelling layer. An analysis strength properties irradiated samples showed decrease resistance cracking destruction main occurred at above 1013 ion/cm2, which are characterized by an excess threshold for overlapping defective regions appear along trajectory incident ions. Tribological tests increase inclusions structure friction crack resistance.
