  Understanding ballistic effects caused by ion beam irradiation, and linking
them with induced structure can be a key point for controlling and predicting
the microstructure of irradiated materials. For this purpose, we have
investigated ballistic effects from an ion mixing formalism point of view. The
displacement cascades in copper and AgCu alloy were obtained using binary
collision approximation (BCA) and molecular dynamics (MD) simulations. We
employed BCA-based code MARLOWE for its ability to simulate high energy
displacement cascades. A first set of simulations was performed using both
methods on pure copper for energies ranging from 0.5 keV to 20 keV. The results
of BCA and MD simulations are compared, evidencing rationally parametrized
MARLOWE to be predictive. A second set of simulations was then carried out
using BCA only. Following experimental studies, AgCu alloy was subjected to 1
MeV krypton ions. MARLOW simulations are found to be in good agreement with
experimental results.
