Abstract :
In this paper, we describe ordering mechanism under irradiation by combining experiments and Kinetic Lattice Monte Carlo (KLMC) simulations on the FePt and FePd equiatomic systems. Both experiments and simulations confirm that our irradiation conditions (small energy transfer, low collision cross section, irradiation temperature under 550K) specifically affect DSRO.
