Monte Carlo simulation of point defects in BCC iron

Recent computer simulations of self-interstitial clusters in BCC iron have revealed that the clusters are highly mobile, and their migration direction is highly anisotropic. These properties may result in high escape ratio of self-interstitial clusters from their nascent cascades, and may affect the...

Description
Summary:Recent computer simulations of self-interstitial clusters in BCC iron have revealed that the clusters are highly mobile, and their migration direction is highly anisotropic. These properties may result in high escape ratio of self-interstitial clusters from their nascent cascades, and may affect the damage recovery process. Using the EAM potential and Langevin equation of motion, we observed the migration process of a tri-interstitial cluster, and estimated rotation energy of larger interstitial clusters.
