Mass density of glassy Pd₈₀Si₂₀ during low-temperature light ion irradiation

Changes in mass density of amorphous Pd 80 Si 20 were monitored in situ during irradiation with He 2+ and H + ions at temperatures below 100 K and during subsequent thermal treatment. The mass density decreased with increasing ion fluence and exponentially approached a saturation value of −1.2%, corresponding to a recombination volume of 190 atomic volumes. The initial swelling rate was 2.3 atomic volumes/displaced atom. The mass density of the irradiated material increased during subsequent thermal treatment, and the irradiation-induced decrease of the mass density recovered completely at room temperature.

The temperature dependence of the defect production has been investigated b y irradiating high purity copper samples with 3 MeV electrons in the temperature range 50 to 207 K.From the initial damage rate the capture radius of the vacancy for migrating interstitials is derived. The observed temperature dependence of the capture radius can be accounted for by a drift diffusion of the interstitials in the elastic strain field of their native vacancy.

“…40 If this were true, a microstructure containing only interstitial loops would give rise to macroscopic swelling, since loops have large positive relaxation volumes and thus induce significant lattice parameter change. 41 However, their relaxation volume is almost compensated by the removal of atoms from some sinks, so swelling due to interstitial loops is nearly zero [Fig. 3(b)].…”

On the relative contributions of point defect clusters to macroscopic swelling of metals

Swelling of metals under irradiation is commonly assessed by calculating the volume fraction of voids, which appear at temperatures where vacancies are mobile. However, other clusters are formed, which may also have an impact on swelling. In particular, interstitial loops have recently been considered to give a significant contribution to swelling owing to their large relaxation volume. In this work, we perform calculations in nickel, based on interatomic potentials, to estimate the contributions of the various point defect clusters. We show that voids produce much more swelling than loops and stacking fault tetrahedra, whose contribution is essentially due to the dislocation core field, inducing a dilatation per unit length of around [Formula: see text], where [Formula: see text] is the Burgers vector. Evaluation of swelling should indeed be done by summing formation volumes, not relaxation volumes, the latter being related to lattice parameter change as measured by x-ray diffraction. We also discuss the case of “lattice swelling” occurring when vacancies are immobile. When self-interstitial atoms cluster as dislocation loops, this swelling mode turns out to be nothing but “void” swelling in a regime where vacancy mobility is so low that vacancies do not cluster appreciably, leaving only interstitial loops visible in transmission electron microscopy.
