Dislocation Pinning in Helium-Implanted Tungsten: A Molecular Dynamics Study
Suchandrima Das, Andrea Sand, Felix Hofmann
The interaction of edge dislocation with helium-implantation-induced defects in tungsten is investigated using molecular dynamics. Following prior investigations, we consider defec…
Microstructure of a heavily irradiated metal exposed to a spectrum of atomic recoils
Max Boleininger, Daniel R. Mason, Andrea E. Sand +1
At temperatures below the onset of vacancy migration, metals exposed to energetic ions develop dynamically fluctuating steady-state microstructures. Statistical properties of these…
Comparison of SIA Defect Morphologies from Different Interatomic Potentials for Collision Cascades in W
Utkarsh Bhardwaj, Andrea E. Sand, Manoj Warrier
The morphology of defects formed in collision cascades is an essential aspect of the subsequent evolution of the microstructure. The morphological composition of a defect decides i…
Graph Theory Based Approach to Characterize Self Interstitial Defect Morphology
Utkarsh Bhardwaj, Andrea E. Sand, Manoj Warrier
The defect morphology is an essential aspect of the evolution of crystals' microstructure and its response to stress. Existing methods either only report defect concentration or ch…
Atomistic-Object Kinetic Monte Carlo simulations of irradiation damage in tungsten
Daniel R. Mason, Andrea E. Sand, Sergei L. Dudarev
We describe the development of a new object kinetic Monte Carlo code where the elementary defect objects are off-lattice atomistic configurations. Atomic-level transitions are used…
Relaxation volumes of microscopic and mesoscopic irradiation-induced defects in tungsten
Daniel R Mason, Duc Nguyen-Manh, Mihai-Cosmin Marinica +2
The low energy structures of irradiation-induced defects have been studied in detail, as these determine the available modes by which a defect can diffuse or relax. As a result, th…
