Isotope effect for diffusion of tin in beta-titanium
The isotope effect for diffusion of in Ti has been measured at five temperatures in the bcc G-phase. Separation of the Sn isotopes was effected by 3-spectroscopy on electroplated sources. The effect is small and highly temperature-dependent, varying from 0.18 ± 0.03 at 9720 C to 0.37 ± 0.03 at …

Diffusion problems in lead-tin overlay bearings
The corrosion of lead-tin overlay bearings in hot lubricating oils, through the depletion of tin in the overlay, has been recognised as a problem of some severity in the automotive bearing industry. The inter-diffusion of tin in the overlay and the copper in the underlying substrate results in the …

Creep behaviour of the ternary lead-free solder alloy : Sn-3.8wt.%Ag-0.7wt.%Cu
Electronic equipment is facing the challenge of both miniaturisation and the need to replace lead in interconnections. In service, interconnections generally fail by thermomechanical fatigue, and this behaviour is strongly affected by the creep process. This thesis examines the creep behaviour of a …
