The radiation-induced vacancy swelling of quasicrystals is considered. In quasicrystals, the dislocation kinetics involves the formation of phasons: vacancy- and interstitial-like localized topological defects. Phasons interact with radiation-induced

At low temperature, T→0, the yield stress of a perfect crystal is equal to its so-called theoretical strength. The yield stress of nonperfect crystals is controlled by the stress threshold of dislocation mobility. A noncrystalline solid has neither

The 2.5 MeV electron-irradiation and resistance-recovery experiments were performed. It was found that the majority of atoms of a (Zr 0.55 Al 0.10 Ni 0.05 Cu 0.30 ) 99 Y 1 bulk metallic glass (BMG) possess a locally preferred order, and vacancies are

We develop a model of the absorption of vacancies and self-interstitial atoms by dislocation loops and associated phason defects in quasicrystals under irradiation. The capture e ciency and the bias of the loop for radiation point defects are evaluat
