Basic Studies of Ion Mixing
Abstract
The objective was to elucidate mechanisms of atomic mixing induced by ions with masses greater than 25 amu and energies between 50 and 500 keV. Specifically, the intent was to identify systematic trends that would reveal the nature of the main parameters that affect atomic rearrangements generated by ion irradiation. In addition, the relationship that might exist between the mechanisms of ion mixing and of thermal processing was to be explored. Metallic systems were to be emphasized. The approach was to choose samples and parameters of irradiation in such a way that the complexity of the results was minimized. The idea was that limiting cases would thereby be established for which one mechanism is dominant. Consequently, experiments at low temperatures have been pursued to investigate processes that are independent of temperature. Irradiations at elevated temperatures were employed to investigate the correlation between ion mixing and thermal processing.
