| Description | Journal: Journal of Physics F: Metal Physics Positron trapping at vacancies and precipitates in copper-indium alloys (3.3 at.% and 7.1 at.% indium) has been studied by positron annihilation measurements using the Doppler-broadening technique. The temperature dependence of the lineshape parameter F shows a strong deviation from the usual S-shaped curves. Difficulties in deducing vacancy formation enthalpies from the data are discussed. Isothermal annealing experiments allow the determination of the positron-precipitate binding energy E_{e+}$^{b}$=0.16+or-0.05 eV as well as the migration energy for interdiffusion $E^{m}$=0.62+or-0.08 eV during the precipitate growth. |
