Atomic displacement processes in irradiated metals

摘要: Abstract Irradiation of solids with energetic particles such as electrons, heavy ions and neutrons, results in the displacement atoms from their lattice sites. In some cases displaced find metastable interstitial sites lattice, leaving vacant behind. other cases, undergo switching processes neighbors. No Frenkel defects are produced but atomic disorder is created. this paper, fundamental theory underlying these presented. Topics include primary recoil spectra, spatial distributions damage energy, defect production, ion beam mixing. addition to traditional analytical theories collisions solids, selected computer simulation presented elucidate discussion introduce latest developments field.
