Abstract: | We test the predictions on the Ni3Al compound by combining molecular dynamics (MD) and KMC simulations. For 1MeV Kr and 70keV He ions, MD simulations are used to simulate the disordered zones, which are then incorporated into KMC simulations to reach long irradiation times. These simulations indicate that 1MeV Kr ion irradiation can lead to patterning, whereas 70keV He ion cannot. Experimentally, we propose to use HRTEM imaging to identify the patterning of chemical order in Ni3Al. |
