Irradiation-induced segregation and diffusion of manganese implants in nickel

Abstract
The effects of radiation-induced solute redistribution and diffusion are studied for 30 keV Mn implants in nickel irradiated with 75 keV Ni+ ions at 500°C. The peak of the Mn implant profile is driven to greater depth with increasing irradiation dose until a steady-state solute profile is established. The rate of drift of Mn atoms and their diffusion coefficient is related to the distribution of point-defects in the nickel under irradiation.
