The co-precipitation of vacancies and carbon atoms in quenched platinum

摘要: Abstract The geometry of secondary defect structures observed in quenched platinum containing various amounts carbon is shown to be consistent with a simple model based on the premise strong impurity (carbon) atom/vacancy binding energy. When ratio atoms vacancies (Cc/Cv) large, co-precipitation as platelets {100} planes occurs; whereas when Cc/Cv small, effects are still manifest; dominated by vacancy behavior, and loops {111} form. Consideration mechanism formation leads conclusions about structure complex, its migration stability. An electron microscopy analysis defects excellent accord proposed model. Implications concerning likely behavior radiation environment considered, an interstitial solute segregation effect sinks predicted.
