Phase formation and stability under 300 keV Cu+ irradiation have been
investigated in Cu/Pd thin films using RBS. The beta phase formation w
as identified by concentration steps in the diffusion profile. These s
teps disappear after irradiation below 423 K at a rate of 1.5 x 10(-4)
dpa/s indicating the dissolution of the beta phase. Irradiation above
503 K at a rate of 1.5 x 10(-2) dpa/s induces growth of the beta phas
e layer. The stability of beta phase under irradiation is interpreted
as a competition between cascade mixing and enhanced diffusion.
