Radiation-Induced Segregation and Precipitation in Ion-Irradiated Molybdenum-Rhenium Alloys

Radiation-induced solute segregation and precipitation in molybdenum-rhenium solid-solution alloys were studied during elevated-temperature helium- and neon-ion irradiation. Radiation-induced segregation of Re atoms in the same direction as the defect fluxes, that is, toward the external surface, was measured during irradiation by in situ Rutherford backscattering spectrometry (RBS). The results of the segregation measurements were in agreement with theoretical models based on point-defect driven transport of solute atoms toward point-defect sinks.
