摘要:
Changes in the distribution of Manganese solute in a 99.8% pure nickel crystal after 75 keV Ni+ion bombardment are reported. Irradiations were performed at 23°C and 500°C at a maximum damage rate of 0.046 dpa/s. The depth profiles of solute impurities near the surface were measured by simultaneous sputter-profiling and Secondary Ion Mass Spectrometry. The results are interpreted in terms of a model of the diffusion and interaction of vacancies, divacancies and self-interstitials. Solute redistribution at 500°C and 23°C is found to be due to the effects of di-vacancy and interstitial fluxes respectively. The relationship of the solute profiles to the point defect distributions is discussed.
