“…atom, at rates, depending on T, lo4 to lo7 times those of Pb. Turner et al [55] discovered that strong internal friction peaks appear in Pb at low temperatures following the dissolution of small amounts of Cu, Ag, or Au. Analysis of the crystallographic dependence of the stress response indicated that the defect responsible for the internal friction has an off-center interstitial configuration which could result from an octahedrally sited interstitial atom pairing with a host atom through displacement along a [loo] direction.…”

Models for the melt → amorphous solid transition and for the structure of amorphous solids in metallic systems will be reviewed. Experience suggests that the tendency toward formation of metallic glasses is greatest in systems composed mainly of noble or certain transition metals (A) admixed with smaller amounts of certain metalloidal or electropositive elements (B). Often the formation of the liquid states of these AB alloys is accompanied by heat evolution, excess entropy of mixing or some volume contraction. The effects of composition on alloy glass forming tendency will be discussed in view of these data and in terms of the structural models alluded to. We note also that the occurrence of ultra-fast impurity diffusion is in alloys where a B type element is the crystalline host and an A type element is the impurity. Experience shows quite conclusively that this rapid transport is effected primarily by interstitial type defects, which must, contrary to the empirical atom size ratio rules for solution behavior, be constituted by substantial proportions of the A component. The recent internal friction studies of Turner and associates suggest that in the lead-noble metal systems the defects have off-center interstitial configurations. We suggest that this interstitial solution behavior may stem from the same type of A-B interactions which are responsible for the strong glass forming tendency in alloys where A is the host. These interactions will be discussed in view of current correlations of alloying behavior

“…With this new criterion for interstitial solid solutions in mind, a number of experimental studies have been made to investigate the existence of interstitial-type defects in metallic systems. Experiments by Rossolimo and Turnbull [45], Turner et al [46,47], Ray et al [48] and Wartburn [49] have shown that for the gold-lead system, at least a fraction of the gold that is in solid solution is dissolved interstitially in the form of defects involving one gold atom. As the temperature is decreased or the concentra tion of gold increased, some of the gold becomes associated into higher order defects (defects involving more than one gold atom).…”
