Atomic Defects in Metals · Zn

This chapter discusses isochronal annealing and differential recovery spectra of yttrium (Y) after low temperature e_--irradiation. However the results are obscured by impurity effects: “superannealing” is observed at T > 140K, and attributed to the redistribution of hydrogen. Although there are no major peaks at lower temperatures the attribution of stage I to the 130K annealing peak must therefore be considered as preliminary. The resistivity per Frenkel defect has been determined from measurements of the damage rate. Self-diffusion has been measured for the α-phase. The isochronal annealing behaviour of zinc (Zn) has also been investigated after e^-- and fast n-irradiations, after irradiation with α-particles and after quenching. Nearly no resistivity increase was observed after plastic deformation up to strain amplitude that leads to failure of samples. The chapter also discusses defect-SA-complexes. Interstitial trapping by Au-SA has been observed by Chann. Vacancy-Ge-SA complexes have been observed by in-beam PAC and a binding energy of E^B ≈ 0.11 eV has been estimated. Properties of Frenkel defects (FD), self-interstitial atoms (SIA), and vacancies (V) in Zn are listed. The V-SA interaction is also tabulated.
